Call Center Management Software Compared to Setting up an Onsite-Based System

More and more people are opting with call center management software because they offer many benefits when compared to premise based systems. There are many different applications that can be used on a shared platform inside of a data center which are then received by agents through IP networks, and these applications allow a business to have a full featured call center system. Some of these applications include speech analytics, workforce management, FVR, predictive dialing, CRM, ACD, and call recording. New eras in customer care are now available thanks to all of these solutions.

Call center management software can extremely reduce up-front costs that are incorporated with setting up onsite premise based equipment and any installation services that may be required. When using hosted solutions the only equipment pieces needed are headsets, broadband connected computers, and agents, which may be located in a call center or at their own residences.

Using a call center management software also allows companies to enjoy the benefits of avoiding paying license fee for new software products, this is because instead they lease the software and pay on a pay as you go basis. This new way of paying for the services is not only economical, its also easier to predict and operate.

Call center-related management software can also be useful in reducing ongoing operational costs. This savings comes from the hosted service provider basically taking on all of the maintenance of the system. This includes any upgrades to the software, replacing any damaged or missing equipment, and any problems with the day-to-day functioning and use of things. When a hosted provider can tend to all of these concerns, it gives a business room to reduce stress and perhaps relieve some of the on-hand IT staff of the pressures of keeping everything running smoothly. It also avoids the need to have specialist IT professionals in some cases. Web-based interfaces also allow for a number of services to be customized, adding value without increasing overall cost.

When companies choose to use an onsite based premise system the set up can be costly and time consuming. Call center management software helps avoid these challenges and offers fast incorporation with any accessible IT systems or any service oriented architecture (SOA). SOA allows businesses to save money by using their already existing software and servers, however, they can access their client information in the same manner they always have.

The best thing about call center management software is that it affords your company with a good many benefits that are inexpensive yet at the same time effective.

Report on VoIP

1.0 Introduction on VoIP:

VoIP is a method to build applications utilizing software and devices. It is just like that network, which carries it, and hence it is not an application. In a VoIP there can be special VoIP server hardware like the analog telephone adapter (ATA), or there can be programmable services that work like a PBX. According to this all the VoIP components must work for the protocol conversation that make the voice, human telephone conversations happen. This means all the VoIP components should follow the same protocol to make that happen.

VoIP is a protocol used to transmit voice over Internet and other packet-switched internet networks. Other names frequently encountered and have the same meaning like the VoIP are IP telephony and Internet telephony, other names like voice over broadband, broadband telephony and broadband phone are given when the network being used is a broadband internet network.

VoIP systems interface with the PSTN for allowing of transparent telecommunication worlwide. There are benefits of VoIP like reducing infrastructure and communication costs as by routing calls on the existing internet networks and avoiding setting up of duplicate networks. Telephony speech signals like digital audio are passed by VoIP systems which are typically cheap in data rates by means of the techniques like communication and data compression. They are packetized into small segments of tens of milliseconds speech and are encapsulated in a packet to transmit it over IP.

Since the first computer networks were developed VoIP has been a area of interest. In 1973 the voice was being transmitted using the internet. In the early 1980s this technology was provided to end users for sending voice conversations on the internet. Then in 1996 VocalTel Internet Phone software which was shrink-wrapped provided VoIP with some additional features like voicemail and caller ID. But this software did not offer gateway to PSTN, hence it was only possible to speak to a user who had VocalTel internet phone. Then the development of first soft switch began, these were developed to replace hardware telephone switches and to serve as gateway between different telephone networks.

2.0 Function of VoIP:

The facilities provided by VoIP would have become more difficult for implementation and can be expensive by using PSTN.

VoIP has the ability to transmit multiple telephone calls using the same internet connection. The services like conferencing, call forwarding, automatic redialling and caller-ID provided by telecom companies would be gained for zero or near zero costs. The calls will be more secure using standardized protocols. Internet connection is needed to connect to a VoIP provider, hence it is location independent. Using VoIP integration with other services that are available on the Internet, which include video conversation, data file or message exchange in parallel to the conversation, audio conferencing, managing address book. Advanced features like computer screen popup, call routing and IVR implementations are much easier and cheaper to integrate and implement.

3.0 Implementation of VoIP:

Transmission of analog signal using switched circuit is the basis of today's PSTN. In contrast to this VoIP networks transmit digitized voice using packet-based systems. As we can see VoIP is providing telephony services at compelling prices. [Syngress, Jason Sinclair, 2002].

Toll Bypass:

In contrast to the internet, PSTN provide voice services with heavy charges or tolls. Toll bypass is one such technique to avoid PSTN charges by using data networks, such like the Internet for carrying voice.

3.1 VoFR

It is a use of frame relay system to transmit IP packets having digitized voice data. Hence it is know as voice over frame relay (VoFR). [Sharma, D., 2002]

3.2 VoATM

It is a use of ATM network to transmit digitalized voice packets. Instead of carrying different length frames an ATM system carries small and fixed length frames known as cells. Hence the name Voice over Asynchronous Transfer Mode (VoATM).

4.0 Security:

VoIP is totally based on network protocols, and it needs to be evaluated from the same perspective when considering the security for a VoIP system [Jim Van Meggelen, Leif Madsen and Jared Smith, 2007]. But this is not to say as to traditional telecom security should be not kept in mind but here we need to give some attention towards the underlying network.

4.1 Basic network security

Single of the majority effective thing that can be complete is to safe access to the voice network. The employ of firewalls and VLANs are example of how this could be achieve. By evade, the voice network be made-up to be reachable only to persons or things that are in need.

4.2 Segregating voice and data traffic

If there is a requirement to have voice and data on the similar network, there may be a few values in maintaining them separately.

4.3 DMZ

Insertion your VoIP network in a DMZ can give an extra layer of security for your

LAN, while unmoving allows connectivity for applicable applications. In spite of whether you set up within a DMZ, any irregular traffic coming out of the network should be suspected.

4.4 Server hardening

Hardening your Asterisk server is serious. Not just are at hand are performances benefits to work on this, the removal of something not necessary will decrease the possibility that an broken vulnerability in the operating method can be utilized to gain admission and start an attack on additional parts of your network. Making Asterisk as non-root is a vital part of system hardening.

4.5 Encryption

Even while Asterisk do not yet fully maintain SRTP, it is still likely to encrypt VoIP transfer. For example, in between sites a VPN might be working.

4.6 Physical security

Physical security must not be unnoticed. All terminate equipments (like switches, routers, and the PBX) should be safe in a situation that can just be accessed by approved persons.

5.0 The Software for VoIP Application:

Asterisk is utilized as an open basis software PBX. At first it was developed in 1999 to meet a telecommunication requires. What meant to be an experiment had progressed into a worldwide phenomenon that changes the face of telecommunication knowledge now and the future. Today, Asterisk is the de facto criterion for voice switching and PBX function in open source space [Jim Van Meggelen, 2007]. Approximately there are 2 million Asterisk servers worldwide and rising. Asterisk gives you real-time connectivity on together PSTN and VoIP networks linking employees working from home to the office PBX over broadband connections. Never in the record of telecommunications has a system so well-matched to the requirements if industry been obtainable, at any price. Asterisk is a facilitate technology and, as by means of Linux, it will turn into increasingly rare to locate an enterprise with the intention of is not running some edition of Asterisk, in some ability, wherever in the netwo rk, solve a problem as just Asterisk can. [Jim Van Meggelen, 2007]

5.1 Benefits of Asterisk Application

Cheap call rates. Administer your telephone arrangement. Fast and easy growth. Situation Integration with business system or existing PBX and VOIP for major savings. No matter of proprietary system Guarded and lithe dial plan. Cheap cost contact to advanced phone Features

5.2 Benefits for Customer

Lower use cost free customer from sole vendor dependency. Provide freedom in system implementation. Eliminate upgrade-path costs. [Phil Lam, 2008] No per-seat license costs. Provides substitute avenues for bear/big fixes. Charge saving on calls.

Asterisk was produced and developed by Digium, Inc. It is a organization based in Huntsville, Alabama who specializes in the development of PBX hardware and open-source telephony software, most notably Asterisk [Digium Inc, 2008]. Digium was founded by Mark Spencer as Linux Support Services in 1999. Contract support and development for Linux were provided by the organization. As Mark did not have the resource to purchase a PBX for his own company, he decided to start writing one from scratch. In 2001, the U.S. economy was going through a period of recession, and as a result demands for the services provided by the company dried up. Mark then took the step to shift the company's focus on its fledgling open-source PBX product, Asterisk. The company was given a new name "Digium" in 2002.

6.0 Asterisk's Requirements:

The source code of asterisk can be downloaded as it is accessable like any other open source softwares, and compile the code by yourself. Asterisk get compiled easily on Linux but it will not even run on FreeBDS, Solaris and Mac OS X. [Ted Wallingford, 2005]. Used in combination with Digul's telephony interface cards, Asterisk offers a strategic, highly cost-effective approach to voice and data transport over IP, TDM, switched and Ethernet architectures. Digium's offerings include VoIP, conferencing, voicemail, legacy PBX, IVR, auto attendant, media servers and gateways, and application servers and gateways.

Many engineers had contributed for the code of asterisk programmed by mark spencer of digium. The engineers were from around the globe. Presently boasting over two million users, wide range of TDM protocols are supported by Asterisk for the handling and transmission of voice over traditional telephony interfaces, featuring VoIP packet protocols such as SIP and IAX. Signaling types that are used in business phones are suppported by U.S and European standard, and they act as a bridge between new-generation voice-data integrated networks and present infrastructure.

7.0 SIP:

SIP [J. Rosenberg, H. Schulzrinne, Camarillo, Johnston, Peterson, Sparks, Handley, and Schooler, 2002.] is a direct (or signalling) protocol similar to HTTP. It is a protocol to can set up and tear along any type of conference. SIP call control uses SDP [M. Handley and V. Jacobson, 1998] to explain the particulars of the call. SIP uses a URI7 to recognize a logical destination, not an IP address. The address might be a nickname, an e-mail address, or even a telephone number. SIP can as well be utilized to send immediate text mails. In the 1960s and 1970s, dumb terminals are used to admission applications on a supercomputer shared by a lot of hundreds of clients. Opening in the 1980s, it began to employ refined application on a PC, but it was also able to employ the PC as a infrastructure terminal to gain admission to applications and database on joint computers (servers) in the network. SIP hosts with a variety of degrees of complexity spirit perform a little function loca lly while allow us to contact application in the network. SIP user can interact openly with these applications.

By using the client-server model, logical entities are defined by SIP that is being implemented jointly or separately in a product. Users send SIP needs, whereas servers admit SIP requests, carry out the request methods, and act in response. The SIP design defines six request methods:

REGISTER allows either the user or a third party to register contact information with a SIP server.

INVITE initiates the call signalling series.

ACK and CANCEL hold session set-up.

BYE terminates a session.

OPTIONS query a server concerning its capabilities.

Registrar is a SIP server that receives, authenticates and accepts REGISTER requests from SIP clients. It may be collocated with a SIP proxy server.

7.1 SIP Soft phones Used:

X-lite, X-Pro and Eyebeam:

Xten Networks invented several VoIP softwares and soft phones. No VoIP test is carried in lab is completed without an X-lite, the company SIP soft phone for windows, Mac, and thin-clients setups. Xten also invented X-Pro, a fully featured business SIP soft phone for Windows, Mac, and MS PocketPC. Xten also produces Eyebeam, a SIP video conference phone. [www.xten.com]

8.0 IAX:

The Inter-Asterisk Exchange Protocol (IAX), currently is in its second revision, is used as a signaling protocol for VoIP networks, just like SIP. End-point and trunk signaling are also provided by this protocol. The main difference in between IAX and the SIP signaling family is that IAX does not implement RTP as the packet mechanism. Instead, IAX has its own way of packaging encoded voice. IAX is also NAT-proof, so dozens or hundreds of simultaneous calls from behind a masquerading firewall will function correctly, just as HTTP does. IAX is implemented in a far-simpler and less application-exhaustive manner than SIP and H.323. It is really intended just for telephony applications, while H.323 and especiallly SIP, include far more extensibility. Therefore IAX is much more packed. All the implementations has been done with as little as 64kb of code. When any IAX client wants to register with the IAX server or proxy, UDP port will be utilized. When again a call is placed, th e same UDP port is used. When again a voice transmits this port is used again. The IAX attaches headers and metadata in each packet that will define what the packets purpose is and whether it has a payload attached to it or not. By this IAX distinguishes between signalling, registration, and voice packets. IAX is an independent protocol created by Mark Spencer rather than a recommended standard like SIP. The specification of IAX has been accepted by the VoIP community though it is proprietary in nature. As a result it is quiet well used in Digium's products. Asterisk the open source PBX implements IAX fully. An ATA is manufactures by Digium too which is IAX based. Digium is also working on manufacturing hadrphones.

8.1 IAX Softphones Used:

8.1.1 Firefly:

Firefly is a softphone produced by Virbiage that implements IAX signalling. It makes it a fine choice for asterisk-based systems or for utilizing services like IAXTel which support the IAX protocol. [www.virbiage.com/firefly]

8.1.2 IAXComm:

IAXComm is an open source softphone for Windows, Linux, and Mac OS X. It is supported by IAX only. [iaxclient.sourceforge.net/iaxcomm]

9.0 Peoples involved in Asterisk:

Mark Spencer / Founder and CTO

While Mark Spencer was a computer engineering student in Auburn University set up a company known as Digium in 1999 with linux support systems. As he was a student it was difficult for him to own PBX, hence with his knowledge of C coding and Linux PC he developed his own PBX for his company. This phenomenon was the starting of an open source known as Asterisk. [Digium Inc, 2008]

As Asterisk attained popularity, Spencer turned his company focus from Linux to supporting Asterisk and expanding up the telecom market. Today digium is the leading open source telecom provider in the world. It happened with Mark using the fledgling start and renaming his company. Mark is know or regarded as pioneer for open source telephony and he gives regular keynote addresses to huge audiences.

David Deaton / Vice President, Engineering

Company's vice president of engineering post was filled by David Deaton in March 2007. Deaton is accountable for overseeing the growth of new Digium products; build upon the achievement of Asterisk NOW and Asterisk Business Edition.

Digium, creator and main developer of Asterisk, the lead open source telephony platform, and Skype, the lead global Internet communications company, has announced the beta version of Skype for Asterisk, which will permit the integration of Skype functionality into Digium's Asterisk software and allow customers to make, receive and transfer Skype calls from within their Asterisk phone systems.

"Throughout our individual histories, Skype and Asterisk have each disrupted conventional communication methods through innovative, cost-effective solutions," said Stefan berg, vice president and general manager for Skype Telecom and Skype for Business. [Digium Inc, 2008]

Particularly, the beta version of Skype for Asterisk is an add-on channel driver module that integrates Skype Internet calling with Asterisk-based telephony products. Skype for Asterisk too complement small and mid-sized business users' existing services on conditional low rates for calling landline and mobile phones around the globe.

10.0 The benefit of Asterisk

10.1 Functionality:

Flexible features are offered by Asterisk based telephony. PBX functionality along with advanced features and interoperatability with standard-based telephony systems , voice over IP systems are offered by Asterisk. The features which large proprietary PBX offers like voicemail, auto attenedent, conference bridging, call queing and many more are done by Asterisk. [Net hawk Pvt. Ltd, 2008]

10.2 Scalability:

VoIP balance or grows much further easily than customary telephone/PBX systems. Adding additional VoIP phone only require connection like receive calls via the office VoIP PBX as condition they were in the office. Asterisk can easily bond two or more branch offices using the Internet. No puzzling codes to dial; all users have their own sole extension. You can just dial directly. As your company expands and you demand more capital from your VoIP systems, there is no requirement to buy new Asterisk software. Server hardware can be improved and/or replaced whereas still retaining your similar Asterisk software, configuration, extensions and voicemail.

10.3 Maintenance:

Routine maintenance and moves-adds-changes will be performed by remote ways as Asterisk is IP based by any friendly representative. Simply a phone can be unpluged from an old location and pluged into new location . graphical user interface makes it easy for adding new users or extensions. [Net hawk Pvt. Ltd., 2008]

10.4 Cost:

Net-Telligence Group has included the Asterisk VoIP platform into a reasonably priced, cost effective explanation that is feature rich, easy to use, constant, scalable and trustworthy.

Three Approaches To Get Substantial PR Backlinks To Your Site

Getting backlinks from software program directories is not a new notion, but it is a very underused method which is strange due to the fact it can have this sort of dramatic results on your over-all search engine rankings. Backlinks from software directories however hold weight with Google (meaning the electrical power of the backlink) since they are so underutilized... The far more a little something is made use of and abused the more quickly Google catches on and reacts accordingly by both cutting down the strength of that type of hyperlink or merely eliminating all power...

For example report directory backlinks utilised to be a valid method for building links... Now it is essentially ineffective when it arrives to gaining back links to your web-site for Web optimization purposes. My rule of thumb is, the easier a link is to get and the extra folks trying to get people hyperlinks, the less electric power a hyperlink hold or the less link juice it provides to your website. This is why software directory inbound links operate so properly... A good deal of persons are not sure how to go about receiving them.

First you need to have some program... You can both get this created, it can be a simple script or a desktop software... You can also try out discovering software package or script with PLR rights, meaning you can do no matter what you want with them, this will get out the element where by you'd have to pay out a coder to make a script for you. The subsequent point you need to have to do after you have the software is make a PAD file... This quite simply describes your application and is wanted in order to submit to any directory...

There are diverse tactics of receiving targeted traffic on your website that can show to be really valuable. Search engine marketing is all about visitors increasing techniques, and a major part of it is based on link developing. It will take some time and function to make your web page search engine friendly, but if you are decided plenty of, you can do it. Individuals use every thing from a person way hyperlinks to reciprocal hyperlinks, despite the fact that most would say the initially choice is far better than the second an individual, to blogs, community forums, articles or blog posts and even getting links. In other words, most folks try each and every procedure obtainable out there, to see which one particular suits them ideal. Commencing to earn funds is extremely hard devoid of possessing website traffic. You can have the most fascinating internet site but it won't make a difference if you can't look to get website traffic to it. You may well be utilizing all the suitable key terms but nevertheless be defeated by a number of competition. If none of the simple solutions look to get the job done for you, it's possible it's time you targeted on a backlink making software program strategy.

Finding traffic is all about excellent top quality marketing. On the other hand, promoting your internet site requires some expertise. You have to know what type of web pages to use and you also have to know how to appeal to viewers.

Catch a Cheating Spouse Online-The Facts - Family

Copyright (c) 2008 Ed Opperman

Marital infidelity has been around since Adam. In this day and age, where computers are a part of daily life, online infidelity has been taken to a whole new level. The computer has good leads to catch your spouse cheating, but first we will look at the downside to the technology.

Chat rooms, dating sites, and pornographic sites are all places where infidelity can start and then grow into a full-fledged affair. Without question, the Internet has made it incredibly easy to find an outlet for cheating on a spouse.

At first, even when you think you have caught a cheating partner, you may be in denial. You might make excuses about how you're the one who is mistaken or over-reacting. Also, you can be sure that the offending spouse will deny it and make excuses. Believe me, there are all kinds of ways they will try to explain it away. The cheater might say that they were just browsing the pics, doing it as a joke, or proclaim complete ignorance of the situation.

The next step you will likely try is to gather additional evidence. After all, if you can catch your spouse cheating, you will have the upper hand. However, cheaters can be very creative in covering their tracks. Besides, they may not even use the home computer to engage in their infidelity; opting for a cyber cafe, or a computer at work.

Now, for the good part. How to catch a cheating spouse can be tricky, but the technology exists to help you catch a cheating spouse online. To up the ante you may try installing what's known as catch a cheating spouse software. This can track the sites they go to, and every word they type into a chat room. That's pretty powerful evidence, but it may not be enough.

Hiring an investigator to find every site they are already registered at is really the only way to remove doubt once and for all. As mentioned, the cheating spouse may not be using a home computer, and you certainly can't install software on someone else's computer. Instead, you can provide the investigator with your spouse's email address, and they can utilize a special search to find exactly what sites they belong to find out if your spouse is cheating.

Sadly, marital infidelity isn't going away. In fact, in many ways it's easier to cheat now than it ever was before. However, the ways to catch a cheating spouse online have kept pace with the changes. There is no need to feel guilty about finding out for sure, so you may as well avail yourself of all the resources that are out there.

Information Technology Explored as a Corporate Asset

It is a significant fact that we are in the focal point of a deep-seated change in both technology and its application. Any institutions in our day expect to get more value from their investments in technology. In the "Post dearth era of calculation" the user-friendliness of dispensation power is not a check where cost of platform technology has become a minor factor in selecting among alternatives to build the business solution and as such the constraining factors are the managerial impact of reengineering the business process and the costs and time required for system development. Additionally, the need to re-educate personnel to the compulsory level of expertise can be an extremely expensive scheme. Open systems enable organizations to buy off-the-shelf solutions to business problems. Open systems standards set apart the design in which data is swapped, remote systems are accessed, and services are attracted. The receipt of open systems standards supports the creation o f system architectures that can be built from technology components. These standards enable us, as follows:
To build reusable class libraries to use in object-oriented design and development environments.
To build functional products those interact with the same data which are bedded on object oriented as well as bedded on full integrity.
To modify a correspondence at an individual desktop workstation to include data, addressing and graphics input from a word processor, a personal spreadsheet, a workgroup database, and an existing project host relevance to be propelled by electronic mail to someplace in the world.
It is worth mentioning that opposing to the claims of groups variety from the Open Software base to the user consortium Open User Recommended Solutions, open systems are not exclusively systems that conform to OSF UNIX specifications. The client/server model makes the enterprise available at the desk. It provides access to data that th e previous architectures did not. Standards have been defined for client-server figuring. If these principles are understood and used, a society can rationally expect to buy solutions today that can grow with their business needs without the constant need to revise the solutions. Architectures based on open systems standards can be implemented throughout the world, as global systems become the norm for large organizations. While a supportable common platform on a global scale is far from standardized, it certainly is becoming much easier to accomplish. From the desktop, enterprise-wide applications are indistinguishable from workgroup and personal applications. Powerful enabling technologies with built-in conformance to open systems standards are evolving rapidly. Examples include object-oriented development, relational and object-oriented databases, multimedia, imaging, expert systems, geographic information systems, voice recognition and voice response, and text management . These technologies provide the opportunity to integrate their generic potentialwith the particular necessities of a businessto create a cost-effective and personalized business solution. The client/server model provides the ideal platform with which to integrate these enabling technologies. Well-defined interface standards enable integration of products from several vendors to provide the right application solution. Enterprise systems are those that create and provide a shared information resource for the entire corporation. They do not imply centralized development and control, but they do treat information and technology as corporate resources. Enterprise network management requires all devices and applications in the enterprise computing environment to be visible and managed. This remains a major challenge as organizations move to distributed processing. Standards are defined and are being implemented within the client/server model. Client/server applications give great er viability to worker empowerment in a distributed organization than do today's host-centered environments.
Prospects are accessible to society and populace who are equipped and capable to compete in the global market and there is no denying the fact that a competitive global economy will ensure obsolescence and obscurity to those who cannot or are unwilling to compete. All organizations must look for ways to demonstrate value. We are in conclusion bearing in mind that an enthusiasm has to rethink upon existing managerial structures and commerce in putting into practice. Organizations are aggressively downsizing even as they try to aggressively expand their revenue base. There is more willingness to continue improvement practices and programs to eliminate redundancy and increase effectiveness. Organizations are becoming market-driven while remaining true to their business vision. To be competitive in a global economy, organizations in developed economies must employ technology to gain the efficiencies necessary to offset their higher labor costs. Reengineering the business process to provide information and decision-making support at points of customer contact reduces the need for layers of decision-making management, improves responsiveness, and enhances customer service. Empowerment means that knowledge and responsibility are available to the employee at the point of customer contact. Empowerment will ensure that product and service problems and opportunities are identified and finalized. Client/server computing is the most effective source for the tools that empower employees with authority and responsibility. The following are some key drivers in organizational philosophy, policies, and practices. Competitiveness is forcing organizations to find new ways to manage their business, despite fewer personnel, more outsourcing, a market-driven orientation, and rapid product obsolescence. Technology can be the enabler of organizational nim bleness. To survive and prosper in a world where trade barriers are being eliminated, organizations must look for partnerships and processes that are not restrained by artificial borders. Quality, cost, product differentiation, and service are the new marketing priorities. Our information systems must support these priorities.
Contesting demands that information systems organizations justify their costs and it is evident that business are in the way to question the return on their existing investments and as such Centralized IS an operation in particular are under the microscope. Manufactured goods obsolescence has never been so vital a factor. Purchasers have more options and are more demanding. Technology must enable organizations to anticipate demand and meet it. Quality and flexibility require decisions to be made by individuals who are in touch with the customer. Many organizations are eliminating layers of middle management. Technology must provide the necessary information and support to this new structure. If a business is run from its distributed locations, the technology supporting these units must be as reliable as the existing central systems. Technology for remote management of the distributed technology is essential in order to use scarce expertise appropriately and to reduce costs. Each individual must have access to all information he or she has a "need and right" to access, without regard to where it is collected, determined, or located. We can use technology today to provide this "single-system image" of information at the desk, whatever the technology used to create it. Standardization has introduced many new suppliers and has dramatically reduced costs. Competition is driving innovation. Organizations must use architectures that take advantage of cost-effective offerings as they appear. Desktop workstations now provide the power and mainframe capacity that mainframes did only a few years ago. The challenge is to effec tively use this power and capacity to create solutions to real business problems. Downsizing and empowerment require that the workgroup have access to information and work collectively. Decisions are being made in the workplace, not in the head office. Standards and new technologies enable workstation users to access information and systems without regard to location. Remote network management enables experts to provide support and central, system-like reliability to distributed systems. However, distributed systems are not transparent. Data access across a network often has unpredictable result sets; therefore, performance on existing networks is often inadequate, requiring a retooling of the existing network infrastructure to support the new data access environment.
Standards enable many new vendors to enter the market. With a common platform target, every product has the entire marketplace as a potential customer. With the high rate of introduction of products, it is certain that organizations will have to deal with multiple vendors. Only through a commitment to standards-based technology will the heterogeneous multiple vendor environment effectively service the buyer. Workstation power, workgroup empowerment, preservation of existing investments, remote network management, and market-driven business are the forces creating the need for client/server computing. The technology is here; what is missing is the expertise to effectively apply it. Organizational pressures to demonstrate value apply as much to the information systems functions as to any other element or operating unit of the business. This is a special challenge because most IS organizations have not previously experienced strong financial constraints, nor have they been measured for success using the same business justification "yardstick" as other value-creating units within the business enterprise. IS has not been under the microscope to prove that the role it plays truly adds value to the overall organization. In today's world, organizations that cannot be seen to add value are either eliminated or outsourced. It has been found out on a survey that about 1000 companies, on average, spend 90 percent of IS dollars maintaining existing systems. Major business benefits, however, are available only from "new" systems. Dramatic reductions in the cost of technology help cost justify many systems. Organizations that adapt faster than their competitors demonstrate value and become the leaders in their marketplace. Products and services command a premium price when these organizations are "early to market." As they become commodities, they attract only commodity prices. This is true of both commercial organizations wishing to be competitive in the market with their products and of service organizations wishing to demonstrate value within their department or government sector. "It only took God seven days to create the world because he didn't have an existing environment to deal with."3 Billions of dollars have been invested in corporate computing infrastructure and training. This investment must be fully used. Successful client/server solutions integrate with the existing applications and provide a gradual migration to the new platforms and business models.
To meet the goals of the 1990s, organizations are downsizing and eliminating middle-management positions. They want to transfer responsibility to empower the person closest to the customer to make decisions. Historically, computer systems have imposed the burden of data collection and maintenance on the front-line work force but have husbanded information in the head office to support decision making by middle management. Information must be made available to the data creators and maintainers by providing the connectivity and distributed management of enterprise databases and applications. The technology of client/server computing will support the movement of information processing to the direct creators and users of information. OLTP applications traditionally have been used in insurance, financial, government, and sales-related organizations. These applications are characterized by their need for highly reliable platforms that guarantee that transactions will be handled correctly, no data will be lost, and response times will be extremely low, and only authorized users will have access to an application. The IS industry understands OLTP in the traditional mainframe-centered platforms but not in the distributed client/server platforms. Organizations do (and will continue) to rely on technology to drive business. Much of the IS industry does not yet understand how to build mission-critical applications on client/server platforms. As organizations move to employee empowerment and workgroup computing, the desktop becomes the critical technology element running the business. Client/server applications and platforms must provide main frame levels of reliability. Executive information systems provide a single-screen view of "how well we are doing" by comparing the mass of details contained in their current and historical enterprise databases with information obtained from outside sources about the economy and competition. As organizations enter into corporation with their customers and suppliers, the need to integrate with external systems becomes essential in order to capture the necessary information for an effective EIS. Organizations want to use the EIS data to make strategic decisions. The DSS should provide "what if" analyses to project the results of these decisions. Managers define expectations, and the local processing capability generates decision alerts when reality does not conform. This is the DSS of the client/server model. Information is now recognized as a corporate resource. To be truly effective, organizations must collect data at the source and distribute it, according to the requiremen ts of "need and right to access," throughout the organization. Workgroups will select the platforms that best meet their needs, and these platforms must integrate to support the enterprise solution. Systems built around open systems standards are essential for cost-effective integration. Los Angeles County issued a request for information stating simply that its goal was "to implement and operate a modern telecommunications network that creates a seamless utility for all County telecommunications applications from desktop to desktop. The United States government has initiated a projectthe National Information Interchange that has the simple objective of "making the intellectual property of the United States available to all with a need and right to access.
"Computers will become a truly useful part of our society only when they are linked by an infrastructure like the highway system and the electric power grid, creating a new kind of free market for information servic es. The feature that makes the highway and electric power grids truly useful is their pervasiveness. Every home and office has ready access to these services; thus, they are usedwithout thoughtin the normal course of living and working. This pervasive accessibility has emerged largely because of the adoption of standards for interconnection. If there were no standards for driving, imagine the confusion and danger. What if every wall plug were a different shape, or the power available on every plug were random? If using a service requires too much thought and attention, that service cannot become a default part of our living and working environment. "Imagine the United States without its highways. Our millions of cars, buses, and trucks driven in our own backyards and neighborhood parking lots, with occasional forays by the daring few along uncharted, unpredictable, and treacherous dirt roads, full of unspeakable terrors."7 The parking lot analogy illustrated in Figure 1.1 re presents the current information-processing environment in most organizations. It is easy and transparent to locate and use information on a local area network (LAN), but information located on another LAN is almost inaccessible. End-user access to enterprise data often is unavailable except for predefined information requests. Although computersfrom mainframes to PCsare numerous, powerful, flexible, and widely used, they are still used in relative isolation. When they communicate, they usually do so ineffectively, through arcane and arbitrary procedures. Information comes with many faces. As shown in Figure 1.2, it can take the form of text, drawings, music, speech, photographs, stock prices, invoices, software, live video, and many other entities. Yet once information is computerized, it becomes a deceptively uniform sequence of ones and zeros. The underlying infrastructure must be flexible in the way it transports these ones and zeros. To be truly effective besides routin g these binaries to their destinations the infrastructure must be able to carry binaries with varying degrees of speed, accuracy, and security to accommodate different computer capabilities and needs. Because computers are manufactured and sold by vendors with differing views on the most effective technology, they do not share common implementation concepts. Transporting ones and zeros around, however flexibly, isn't enough. Computers based on different technologies cannot comprehend each other's ones and zeros any more than people comprehend foreign languages. We therefore need to endow our IS organizations with a set of widely understood common information interchange conventions. Moreover, these conventions must be based on concepts that make life easier for humans, rather than for computer servants. Finally, the truly useful infrastructure must be equipped with "common servers"computers that provide a few basic information services of wide interest, such as computerized white and yellow pages.

Technological innovation proceeds at a pace that challenges the human mind to understand how to take advantage of its capabilities. Electronic information manageme nt, technological innovation in the personal computer, high-speed electronic communication, and digital encoding of information provide new opportunities for enhanced services at lower cost. Personal computers can provide services directly to people who have minimal computer experience. They provide low-cost, high-performance computing engines at the site that the individual lives, works, or accesses the serviceregardless of where the information is physically stored. Standards for user interface, data access, and intercrosses communications have been defined for the personal computer and are being adopted by a majority of the vendor community. There is no reason to accept solutions that do not conform to the accepted standards. Most large organizations today use a heterogeneous collection of hardware, software, and connectivity technologies. There is considerable momentum toward increased use of technology from multiple vendors. This trend leads to an increasingly heterogen eous environment for users and developers of computer systems. Users are interested in the business functionality, not the technology. Developers rarely are interested in more than a subset of the technology. The concept of the single-system image says that you can build systems that provide transparency of the technology platform to the user andat the largest extent possibleto the developer. Developers will need sufficient knowledge of the syntax used to solve the business problem, but will need little or no knowledge of the underlying technology infrastructure. Hardware platforms, operating systems, database engines, and communications protocols are necessary technological components of any computer solution, but they should provide servicesnot create obstacles to getting the job done. Services should be masked; that is, they should be provided in a natural manner without requiring the user to make unnatural gyrations to invoke them. Only by masking these services and by u sing standard interfaces can we hope to develop systems quickly and economically. At the same time, masking (known as encapsulation in object-oriented programming) and standard interfaces preserve the ability to change the underlying technology without affecting the application. There is value in restricting imagination when you build system architectures. Systems development is not an art; it is an engineering discipline that can be learned and used. Systems can be built on the foundations established by previous projects.
Within the single-system image environment, a business system user is totally unaware of where data is stored, how the client and server processors work, and what networking is involved in gaining connectivity. Every application that the user accesses provides a common "look and feel." Help is provided in the same way by every application. Errors are presented and resolved in the same way by every application. Access is provided through a standard security procedure for every application. Each user has access to all services for which he or she has a need and a right to access.
The security layer is invisible to the authorized and impenetrable to the unauthorized.
Navigation from function to function and application to application is provided in the same way in every system. New applications can be added with minimal training, because the standard functions work in the same way, and only the new business functions need be learned. It is not necessary to go to "boot camp for basic training" prior to using each new application. Basic training is a one-time effort because the basics do not change.
The complexity of a heterogeneous computing platform will result in many interfaces at both the logical and physical level. Organizations evolve from one platform to another as the industry changes, as new technologies evolve that are more cost effective, and as acquisitions and mergers introduce other in stalled platforms. All these advances must be accommodated. There is complexity and risk when attempting to interoperate among technologies from many vendors. It is necessary to engage in "proof of concept" testing to distinguish the marketing version of products and architectures from the delivered version. Many organizations use a test lab concept called technology competency centers to do this "proof of concept." The TCC concept provides a local, small-scale model of all the technologies involved in a potential single-system, interoperable image. Installing a proposed solution using a TCC is a low-cost means of ensuring that the solution is viable. These labs enable rapid installation of the proposed solution into a proven environment. They eliminate the need to set up from scratch all the components that are necessary to support the unique part of a new application. OrganizationsMerrill Lynch, Health Canada, SHL System house, BSG Corporation, Microsoft, and many othersus e such labs to do sanity checks on new technologies. The rapid changes in technology capability dictate that such a resource be available to validate new products. The single-system image is best implemented through the client/server model.. Our experience confirms that client/server computing can provide the enterprise to the desktop. Because the desktop computer is the user's view into the enterprise, there is no better way to guarantee a single image than to start at the desktop. Unfortunately, it often seems as if the number of definitions of client/server computing depends on how many organizations you survey, whether they're hardware and software vendors, integrators, or IS groups. Each has a vested interest in a definition that makes its particular product or service an indispensable component. Throughout this book, the following definitions will be used consistently:
Client: A client is a single-user workstation that provides presentation services and the app ropriate computing, connectivity, and database services and interfaces relevant to the business need.
Server: A server is one or more multi-user processors with shared memory providing computing, connectivity, and database services and interfaces relevant to the business need.
Client/server computing is an environment that satisfies the business need by appropriately allocating the application processing between the client and the server processors. The client requests services from the server; the server processes the request and returns the result to the client. The communications mechanism is a message passing interposes communication (IPC) that enables (but does not require) distributed placement of the client and server processes. Client/server is a software model of computing, not a hardware definition. This definition makes client/server a rather generic model and fits what is known in the industry as "cooperative processing" or "peer-to-peer." Because the client/server environment is typically heterogeneous, the hardware platform and operating system of the client and server are not usually the same. In such cases, the communications mechanism may be further extended through a well-defined set of standard application program interfaces (APIs) and remote procedure calls. The modern diagram representing the client/server model was probably first popularized by Sybase. Figure 1.4 illustrates the single-system image vision. A client-user relies on the desktop workstation for all computing needs. Whether the application runs totally on the desktop or uses services provided by one or more serversbe they powerful PCs or mainframesis irrelevant. Effective client/server computing will be fundamentally platform-independent. The user of an application wants the business functionality it provides; the computing platform provides access to this business functionality. There is no benefit, yet considerable risk, in exposing this platfo rm to its user. Changes in platform and underlying technology should be transparent to the user. Training costs, business processing delays and errors, staff frustration, and staff turnover result from the confusion generated by changes in environments where the user is sensitive to the technology platform.

It is easily demonstrated that systems built with transparency to the technology, for all users, offer the highest probability of solid ongoing return for the technology investment. It is equally demonstrable that if developers become aware of the target platform, development will be bound to that platform. Developers will use special features, tricks, and syntax found only in the specific development platform. Tools, which isolate developers from the specifics of any single platform, assist developers in writing transparent, portable applications. These tools must be available for each of the three essential components in any application: data access, proce ssing, and interfaces. Data access includes the graphical user interface (GUI) and stored data access. Processing includes the business logic. Interfaces link services with other applications. This simple model, reflected in Figure 1.5, should be kept in mind when following the evolution to client/server computing. The use of technology layers provides this application development isolation. These layers isolate the characteristics of the technology at each level from the layer above and below. This layering is fundamental to the development of applications in the client/server model. The rapid rate of change in these technologies and the lack of experience with the "best" solutions implies that we must isolate specific technologies from each other. This book will continue to emphasize and expand on the concept of a systems development environment (SDE) as a way to achieve this isolation. Developer tools are by far the most visible. Most developers need to know only the synt ax of these tools to express the business problem in a format acceptable to the technology platform. With the increasing involvement of minicomputer professionals, as technology users and application assemblers, technology isolation is even more important. Very fewperhaps noneof an organization's application development staff needs to be aware of the hardware, system software, specific database engines, specific communications products, or specific presentation services products. These are invoked through the APIs message passing, and generated by tools or by a few technical specialists. As you will see in Chapter 6, the development of an application architecture supported by a technical architecture and systems development environment is the key to achieving this platform independence and ultimately to developing successful client/server applications.
As organizations increase the use of personal productivity tools, workstations become widely installed. The need to p rotect desktop real estate requires that host terminal capabilities be provided by the single workstation. It soon becomes evident that the power of the workstation is not being tapped and application processing migrates to the desktop. Once most users are connected from their workstation desktop to the applications and data at the host mainframe or minicomputer, there is significant cost benefit in offloading processing to these powerful workstations. The first applications tend to be data capture and edit. These simplifybut still usethe transaction expected by an already existing host application. If the workstation is to become truly integrated with the application, reengineering of the business process will be necessary. Accounting functions and many customer service applications are easily offloaded in this manner. Thus, workgroup and departmental processing is done at the LAN level, with host involvement for enterprise-wide data and enforcement of interdepartmental bus iness rules. In this "dumb" terminal (IBM uses the euphemism nonprogrammable to describe its 327x devices) emulation environment, all application logic resides in the minicomputer, mainframe, or workstation. Clearly a $5000 or less desktop workstation is capable of much more than the character display provided by a $500 terminal. In the client/server model, the low-cost processing power of the workstation will replace host processing, and the application logic will be divided appropriately among the platforms. As previously noted, this distribution of function and data is transparent to the user and application developer.
The mainframe-centric model uses the presentation capabilities of the workstation to front-end existing applications. The character mode interface is remapped by products such as Easel and Mozart. The same data is displayed or entered through the use of pull-down lists, scrollable fields, check boxes, and buttons; the user interface is easy to use, a nd information is presented more clearly. In this mainframe-centric model, mainframe applications continue to run unmodified, because the existing terminal data stream is processed by the workstation-based communications API. This protects the investment in existing applications while improving performance and reducing costs. Character mode applications, usually driven from a block mode screen, attempt to display as much data as possible in order to reduce the number of transmissions required to complete a function. Dumb terminals impose limitations on the user interface including fixed length fields, fixed length lists, crowded screens, single or limited character fonts, limited or no graphics icons, and limited windowing for multiple application display. In addition, the fixed layout of the screen makes it difficult to support the display of conditionally derived information. In contrast, the workstation GUI provides facilities to build the screen dynamically. This enables screens to be built with a variable format based conditionally on the data values of specific fields. Variable length fields can be scrollable, and lists of fields can have a scrollable number of rows. This enables a much larger virtual screen to be used with no additional data communicated between the client workstation and server. Windowing can be used to pull up additional information such as help text, valid value lists, and error messages without losing the original screen contents. The more robust GUI facilities of the workstation enable the user to navigate easily around the screen. Additional information can be encapsulated by varying the display's colors, fonts, graphics icons, scrollable lists, pull-down lists, and option boxes. Option lists can be provided to enable users to quickly select input values. Help can be provided, based on the context and the cursor location, using the same pull-down list facilities. Although it is a limited use of client/server comput ing capability, a GUI front end to an existing application is frequently the first client/server-like application implemented by organizations familiar with the host mainframe and dumb-terminal approach. The GUI preserves the existing investment while providing the benefits of ease of use associated with a GUI. It is possible to provide dramatic and functionally rich changes to the user interface without host application change.
The next logical step is the provision of some edit and processing logic executing at the desktop workstation. This additional logic can be added without requiring changes in the host application and may reduce the host transaction rate by sending up only valid transactions. With minimal changes to the host application, network traffic can be reduced and performance can be improved by using the workstation's processing power to encode the data stream into a compressed form. A more interactive user interface can be provided with built-in, conte xt-sensitive help, and extensive prompting and user interfaces that are sensitive to the users' level of expertise. These options can be added through the use of workstation processing power. These capabilities enable users to operate an existing system with less intensive training and may even provide the opportunity for public access to the applications. Electronic data interchange (EDI) is an example of this front-end processing. EDI enables organizations to communicate electronically with their suppliers or customers. Frequently, these systems provide the workstation front end to deal with the EDI link but continue to work with the existing back-end host system applications. Messages are reformatted and responses are handled by the EDI client, but application processing is done by the existing application server. Productivity may be enhanced significantly by capturing information at the source and making it available to all authorized users. Typically, if users employ a multipart form for data capture, the form data is entered into multiple systems. Capturing this information once to a server in a client/server application, and reusing the data for several client applications can reduce errors, lower data entry costs, and speed up the availability of this information.
There is no delay while the forms are passed around the organization. This is usually a better technique than forms imaging technology in which the forms are created and distributed internally in an organization. The use of workflow-management technology and techniques, in conjunction with imaging technology, is an effective way of handling this process when forms are filled out by a person who is physically remote from the organization. Intelligent Character Recognition (ICR) technology can be an extremely effective way to automate the capture of data from a form, without the need to key. Current experience with this technique shows accuracy rates greater than 99.5 per cent for typed forms and greater than 98.5 percent for handwritten forms.

Rightsizing and rationalizing are strategies used with the client/server model to take advantage of the lower cost of workstation technology. Rightsizing and upsizing may involve the addition of more diverse or more powerful computing resources to an enterprise computing environment. The benefits of rightsizing are reduction in cost and/or increased functionality, performance, and flexibility in the applications of the enterprise. Significant cost savings usually are obtained from a resulting reduction in employee, hardware, software, and maintenance expenses. Additional savings typically accrue from the improved effectiveness of the user community using client/server technology. Eliminating middle layers of management implies empowerment to the first level of management with the decision-making authority for the whole job. Information provided at the desktop by networked PCs and workstat ions integrated with existing host (such as mainframe and minicomputer) applications is necessary to facilitate this empowerment. These desktop-host integrated systems house the information required to make decisions quickly. To be effective, the desktop workstation must provide access to this information as part of the normal business practice. Architects and developers must work closely with business decision makers to ensure that new applications and systems are designed to be integrated with effective business processes. Much of the cause of poor return on technology investment is attributable to a lack of understanding by the designers of the day-to-day business impact of their solutions. Downsizing information systems is more than an attempt to use cheaper workstation technologies to replace existing mainframes and minicomputers in use. Although some benefit is obtained by this approach, greater benefit is obtained by reengineering the business processes to really use the capabilities of the desktop environment. Systems solutions are effective only when they are seen by the actual user to add value to the business process. Client/server technology implemented on low-cost standard hardware will drive downsizing. Client/server computing makes the desktop the users' enterprise. As we move from the machine-centered era of computing into the workgroup era, the desktop workstation is empowering the business user to regain ownership of his or her information resource. Client/server computing combines the best of the old with the newthe reliable multi-user access to shared data and resources with the intuitive, powerful desktop workstation.
In view of the above it is evident that object-oriented development concepts are embodied in the use of an SDE created for an organization from an architecturally selected set of tools. The SDE provides more effective development and maintenance than companies have experienced with traditional host-base d approaches. Client/server computing is open computing. Mix and match is the rule. Development tools and development environments must be created with both openness and standards in mind. Mainframe applications rarely can be downsizedwithout modificationsto a workstation environment. Modifications can be minor, wherein tools are used to port existing mainframe source codeor major, wherein the applications are rewritten using completely new tools. In porting, native COBOL compilers, functional file systems, and emulators for DB2, IMS DB/DC, and CICS are available for workstations. In rewriting, there is a broad array of tools ranging from PowerBuilder, Visual Basic, and Access, to larger scale tools such as Forte and Dynasty. Micro Focus has added an Object Oriented (OO) option to its workbench to facilitate the creation of reusable components. The OO option supports integration with applications developed under Smalltalk/V PM. IBM's CICS for OS/2, OS400, RS6000, and HP/UX p roducts enable developers to directly port applications using standard CICS call interfaces from the mainframe to the workstation. These applications can then run under OS/2, AIX, OS400, HP/UX, or MVS/VSE without modification. This promises to enable developers to create applications for execution in the CICS MVS environment and later to port them to these other environments without modification. Conversely, applications can be designed and built for such environments and subsequently ported to MVS (if this is a logical move). Organizations envisioning such a migration should ensure that their SDE incorporates standards that are consistent for all of these platforms.
These harvests, pooled with the economical processing power available on the workstation, make the workstation Local Area Network an ideal expansion and maintenance environment for existing host processors. When an organization views mainframe or minicomputer resources as real dollars, developers can usua lly justify offloading the development in only three to six months. Explorers can be effective only when a proper systems development environment is put in place and provided with a suite of tools offering the host capabilities plus enhanced connectivity. Workstation operating systems are still more primitive than the existing host server MVS, VMS, or UNIX operating systems. Therefore, appropriate standards and procedures must be put in place to coordinate shared development. The workstation environment will change. Only projects built with common standards and procedures will be resilient enough to remain viable in the new environment.
The major reserves come up to from new projects that can create apposite values at the initiate and do all development using the workstation LAN environment. It is possible to retrofit standards to an existing environment and establish a workstation with a LAN-based maintenance environment. The benefits are less because retrofitting th e standards creates some costs. However, these costs are justified when the application is scheduled to undergo significant maintenance or if the application is very critical and there is a desire to reduce the error rate created by changes. The discipline associated with the movement toward client/server-based development, and the transfer of code between the host and client/server will almost certainly result in better testing and fewer errors. The testing facilities and usability of the workstation will make the developer and tester more effective and therefore more accurate. Business processes use database, communications, and application services. In an ideal world, we pick the best servers available to provide these services, thereby enabling our organizations to enjoy the maximum benefit that current technology provides. Real-world developers make compromises around the existing technology, existing application products, training investments, product support, and a my riad other factors. Key to the success of full client/server applications is selecting an appropriate application and technical architecture for the organization. Once the technical architecture is defined, the tools are known.
The ultimate pace is to accomplish an SDE to categorize the principles desirable to use the tools in actual fact. This SDE is the collection of hardware, software, standards, standard procedures, interfaces, and training built up to support the organization's particular needs. Many construction projects fail because their developers assume that a person with a toolbox full of carpenter's tools is a capable builder.

In view of the above, it is evident that in order to be a successful planner, a person needs be trained to build according to standards. The creation of standards to define interfaces to the sewerage, water, electrical utilities, road, school, and community systems is essential for successful, cost-effective building. We do no t expect a carpenter to design such interfaces individually for every building. Rather, pragmatism discourages imagination in this regard. By reusing the models previously built to accomplish integration, we all benefit from cost and risk reduction. Suffice it to say that the preamble of a whole new generation of Object oriented Technology based on tools for client/server development demands that proper standards can be put in place to support shared development, reusable code, interfaces to existing systems, security, error handling, and an organizational standard "gaze and think." As with any new technology, there will be changes. Developers can build application systems closely tied to today's technology or use an SDE and promote applications that can progress along with the expertise podium.
