e-business Architecture - Glossary

There are two basic categories of businesses conducted over the Internet. The first category is the
  1. Business-to-Consumer (B2C) segment, which includes the popular, Wall Street-friendly businesses like Amazon, E*Trade, etc.
  2. The second is the Business-to-Business (B2B) segment, which is in- creasingly overshadowing the B2C segment and includes such names as Chemtex and AutoExchange.
Despite fundamental differences in the business models of these two categories, they share one common key aspect which is use of Internet technologies to manage all aspects of the business. This article presents an integrated architecture for these Internet technologies so that organizations can effectively implement whichever type of business model they choose.
Active Server Pages
A Microsoft solution for dynamically created Web pages created by a server, used when a page is requested by the client. This enables the page to contain information from a database.
A set of rules for how applications should share information. This is Microsoft's version of Java applets.
(Asymmetric digital subscriber line) Technology that allows more data to be sent over existing copper phone lines. ADSL supports data transfer rates of 1.5 to 9Mbps when receiving data (downstream rate) and from 16 to 640 Kbps when sending data (upstream rate).
Analytics are the ability to understand B2C site visitor behavior and traffic patterns, and site effectiveness.
A set of routines, protocols, and tools for building software applications. Good APIs make it easier to develop a program by providing all needed building blocks.
Application servers
A program run on a mid-sized machine that handles all applications operations between browser -based computers and a company's back-end business applications or databases. Because many databases cannot interpret commands written in HTML, the application server works as a translator, allowing, for example, a customer with a browser to search an online retailer's database for pricing information. Application servers are seen as filling a large and growing market; more than 25 companies now offer such products.
Application Service Provider
Application Service Providers are third-party entities that host (manage and distribute) software-based services and solutions to customers across a wide area network from a central data center. Do not confuse this acronym with Active Server Pages (ASP). ASP is a form of applications outsourcing.
For purposes of this course, architecture is the structure or design of an eBusiness.
May refer either Active Server Pages or Application Service Providers. These are two different concepts.
Asynchronous Transfer Mode
Is a means of transferring data across a network in the form of packets or cells with a fixed size.
Automatic Teller Machines
Machine that lets you do your banking without dealing with a person. At ATMs, you can take cash from your account, make deposits and move money between accounts. All you need is a password you key in and an access card. Do not confuse the acronym ATM with Asynchronous Transfer Mode, which is a means of transferring data across a network in the form of packets or cells with a fixed size.
A primary Business model where the buyer and seller are both businesses. This would be the case for a wholesale stationer selling stock to retail outlets.
A primary two-business model where the seller is a business and the buyer is a consumer or individual such as with a bookstore that sells books to the public.
The amount of data that can be transmitted in a fixed amount of time. For digital devices, the bandwidth is usually expressed in bits per second(bps) or bytes per second.
Generally, the study of measurable biological characteristics. In computer security biometrics refers to authentication techniques that rely on measurable physical characteristics that can be automatically checked. Examples include computer analysis of fingerprints or speech.
A bot is a software tool for digging through data. Sometimes referred to as an Agent. You give a bot directions and it brings back answers. Bots were used as early as the first Net newsgroups. There are different kinds of bots. For example, a service bot they might answer specific questions about a product or service.
Device that connects two local area networks (LANs) or elements of the same LAN. The two LANs being connected can be alike or dissimilar. Unlike routers, bridges are protocol-independent. They simply forward packets of data without analyzing and re-routing messages. Consequently, they're faster than routers, but also less versatile.
Browse-to-buy ratio
Ratio of number of shoppers viewing the products to the number that purchase. Although it is important to get more people to view your products, it is even more important that some buy the product. A high Browse-to-buy ratio indicates that not many browsers are buying which could indicate a problem with pricing or the shopping mechanism.
Business to Business
A primary Business model where the buyer and seller are both businesses. This would be the case for a wholesale stationer selling stock to retail outlets. Also known as B2B.

An application that runs on a computer that connects to a server. The client relies on the server to perform certain operations. The term Client can also encompass the hardware on which the client software runs. A Web browser such as Netscape Communicator or Microsoft Internet Explorer is a client that relies on a Web server to provide content.
Client configuration
The hardware and software configuration of a client including user defined settings, available hardware and software setup.
Closed standard
Closed systems or standards are based on proprietary standards. They are usually unique to a single vendor and are not compatible with offerings from other vendors. The opposite of closed standards are open standards.
Co-location facility
Co-location facilities offer the customer a secure place to physically house their hardware and equipment as opposed to locating it in their offices or warehouse where the potential for fire, theft or vandalism is much greater. Most co-location facilities offer high-security, including cameras, fire detection and extinguishing devices, multiple connection feeds, filtered power, backup power generators and other items to ensure high-availability which is mandatory for all Web-based, virtual businesses.

Computer Aided Design/Computer Aided Manufacture
CAD or Computer Aided Design makes use of powerful computer hardware and software to enable engineers and architects to design objects. CAM or Computer Aided Manufacturing is where computers assist in the manufacturing of items in a factory. CAD/CAM implies a link between the two. Once a designer has created the design specification, the computer will assist to make the product.
Connectivity resources
Connectivity resources refer to the network infrastructure required to connect a computer and its contents to other computers. This includes physical devices like modems, switches, hubs, routers, bridges, cabling and satellite links as well as network protocols, operating systems and security systems.
Consumer to Consumer
A Business model where the buyer and seller are both consumers. An example might be the trade that takes place on an auction site.
A cookie is a message given to a Web browser by a Web server. The browser stores the message in a text file called cookie.txt. The message is then sent back to the server each time the browser requests a page from the server.
(Common Object Request Broker Architecture) Enables pieces of programs, called objects, to communicate with one another regardless of what operating system they are running on or what programming language they were written in. Developed by OMG (Open Management Group). Corba Fundamentals
Data packet
A piece of a message transmitted over a packet-switching network. One of the key features of a packet is that it contains the destination addres in addition to the data. In IP networks, packets are often called datagrams.
Database Management Systems
DBMS or Database Management Systems are a collection of programs that enable the storing, modification and extraction of data to and from a database. DBMS
Denial-of-service attack
A type of attack that is designed to disable a computer or network by flooding it with useless traffic.
Produces Web content that changes each time it is viewed. For example, the same URL could result in a different page depending on any number of parameters including previous pages viewed by the reader, profile of the reader, time of day, etc. Very similar to active server pages (ASP).

Refers to trade (buying and selling products and services) that actually takes place over the Internet; sometimes referred to as iCommerce.
Covers the transfer of data between different companies using networks, such as the Internet. These standards allow documents such as purchasing orders, shipping documents, and invoices to be transferred from business to business.
Enterprise Java Beans (EJB)
Component software architecture from Sun that is used to build Java applications that run in the server. It uses a "container" layer that provides common functions such as security and transaction support and delivers a consistent interface to the applications regardless of the type of server. CORBA is the infrastructure for EJBs, and at the wire level, EJBs look like CORBA components. EJBs are the backbone of Sun's J2EE platform, which provides a pure Java environment for developing and running Web-based applications.
Enterprise portal
A Web site that provides information and services to a particular industry. It is the industry-specific equivalent of the general-purpose portal on the Web.
eProcurement hub
Are similar to catalog hubs but are not industry specific; also known as MRO hubs.
Space on a Web server where Web pages and content may be stored.
A retailer that uses the Internet as a medium for selling products.
Exchange hub
Matches buyers in an industry with a supplier, by facilitating a temporary relationship between the buyer and seller based on supply and demand.
Refers to an intranet that is partially accessible to authorized outsiders. Whereas an intranet resides behind a firewall and is accessible only to people who are members of the same company or organization, an extranet provides various levels of accessibility to outsiders. An extranet may provide access to paid research, current inventories and internal databases, virtually any information that is private and not publically available. You can access an extranet only if you have a valid username and password, and your identity determines which parts of the extranet you can view.
Fault tolerance functionality
The ability of a system to respond gracefully to an unexpected hardware or software failure. There are many levels of fault tolerance, the lowest being the ability to continue operation in the event of a power failure. Many fault-tolerant computer systems mirror all operations, that is, every operation is performed on two or more duplicate systems, so if one fails the other can take over.
Fiber optic
A technology used for transmitting data by light. A fiber optic cable consists of thin strands of glass or plastic along which the light can travel.
A method for keeping a network secure. It can be implemented in a single router that filters out unwanted packets, or it may use a combination of technologies in routers and hosts. Firewalls are widely used to give users access to the Internet in a secure fashion as well as to separate a company's public Web server from its internal network. They are also used to keep internal network segments secure. For example, a research or accounting subnet might be vulnerable to snooping from within.
The index or home page on a Web site.
The protocol used for transferring files over the Internet.
The process of planning and executing the logistics regarding the fulfillment of orders.
In networking, a combination of hardware and software that links two different types of networks.

Horizontal hub
Automate a business function or procedure across domains; are also known as Functional hubs.
The authoring language used to create documents on the World Wide Web.
HyperText Transfer Protocol, the underlying protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page.
A business that connects multiple buyers and sellers together electronically.
An element in an electronic document that links to another place either within the same document or in a different document. Typically, the user clicks the hyperlink to follow the link.
(Internet Content Exchange Protocol) This defines the method and format for content exchange and provides support for management and control of syndication relationships. ICE is an application of XML.

Some companies refer to this department as IS (Information Services) or MIS (Management Information Services).
A go-between acting as a link between parties.
A global network connecting millions of computers that are joined through a high-speed backbone of data links.
A network based on TCP/IP protocols (an internet) belonging to an organization, usually a corporation, accessible only by the organization's members, employees, or others with authorization. An in-house Web site that serves the employees of the enterprise. Although intranet pages may link to the Internet, an intranet is not a site accessed by the general public. Using programming languages such as Java, client/server applications can be built on intranets. Since Web browsers that support Java run under Windows, Mac and UNIX, such programs also provide cross-platform capability. Intranets use the same communications protocols and hypertext links as the Web and thus provide a standard way of disseminating information internally and extending the application worldwide at the same time. An intranet looks and behaves like any other Web site, but is protected from unauthorized access by a firewall.
(Internet Server API) A programming interface on Internet Information Server (IIS), Microsoft's Web server. Using ISAPI function calls, Web pages can invoke programs that are written as DLLs on the server, typically to access data in a database. IIS comes with a DLL that allows embedded queries to access ODBC-compliant databases. ISAPI is an alternative to using CGI scripts on Microsoft Web servers. The counterpart to ISAPI on the client side is WinInet.
Integrated services digital network) An international communications standard for sending voice, video and data over digital phone lines or normal phone wires. ISDN supports data transfer rates of 64 Kbps (64000 bits per second). Most ISND lines offer. Most ISDN services include two lines at once. When both are used, the data rate of 128 Kbps is three times the data rate provided by today's fastest modem. The latest version of ISDN, B-ISDN supports transmission rates of 1.5 Mbps and requires fiber optic cables.
(Internet Service Provider) An organization that provides access to the Internet. Small Internet service providers (ISPs) provide service via modem and ISDN while the larger ones also offer private line hookups (T1 or fractional T1). Customers are generally billed a fixed rate per month, but other charges may apply. For a fee, a Web site can be created and maintained on the ISP's server, allowing the smaller organization to have a presence on the Web with its own domain name.
ISPs(Internet Service Provider)
A company that provides access to the Internet. For a monthly fee, the service provider gives you a software package, username, password and access phone number. Equipped with a modem, you can then log on to the Internet and browse the World Wide Web and USENET, and send and receive e-mail.
(Java 2 Enterprise Edition) A server-side eBusiness application that provides several basic constructs and features that are useful in server-side eBusiness computing. It also includes a messaging protocol (JMS, short for Java Messaging Service), supports multithreading, runs cross-operating systems, offers XML support, provides database integration (through JDBC), and a rich set of low-level objects and services that support security, network awareness, and software management.
A programming language for writing client and server applications for the Web. Developed by Sun, Java was modeled after C++, and Java programs can be called from within HTML documents or launched stand-alone. When a Java program runs from a Web page, it is called a "Java applet." When a Java program is run on the Web server, it is called a "servlet." The first Web browsers to run Java applications were Sun's HotJava and Netscape's Navigator 2.0. Java was designed to run in small amounts of memory and provides enhanced features for the programmer, including the ability to release memory when no longer required.
Allow developers to create reusable software components that can then be assembled together using visual application builder tools.
(Java Database Connectivity) A programming interface that lets Java applications access a database via the SQL language. Since Java interpreters (Java Virtual Machines) are available for all major client platforms, this allows a platform-independent database application to be written. In 1996, JDBC was the first extension to the Java platform. JDBC is the Java counterpart of Microsoft's ODBC.

A booth providing a computer-related service. A kiosk requires a simple user interface that can be used without training or documentation, and the hardware must be capable of operating unattended for long periods of time. Touch screens can provide some of these features because they enable a user to enter and display information on the same device and eliminate the need for keyboards, which are prone to break.
Legacy applications
An application in which a company or organization has already invested considerable time and money. Typically, legacy applications are database management systems (DBMSs) running on mainframes or minicomputers. An important feature of new software products is the ability to work with a company's legacy applications, or at least be able to import data from them.
Legacy systems
Legacy systems support legacy applications.
Lightweight Directory Access Protocol (LDAP)
Lightweight Directory Access Protocol, a set of protocols for accessing information directories. LDAP is based on the standards contained within the X.500 standard, but is significantly simpler. And unlike X.500, LDAP supports TCP/IP, which is necessary for any type of Internet access. Because it's a simpler version of X.500, LDAP is sometimes called X.500-lite. Although not yet widely implemented, LDAP should eventually make it possible for almost any application running on virtually any computer platform to obtain directory information, such as email addresses and public keys. Because LDAP is an open protocol, applications need not worry about the type of server hosting the directory.
A version of UNIX that runs on x86, Alpha and PowerPC machines. Linux is open source software, which is freely available; however, the full distribution of Linux along with technical support and training are available for a fee from vendors. The distribution CD-ROMs includes the complete source code as well as hundreds of tools, applets and utilities. Due to its stability, Linux has gained popularity with ISPs as the OS for hosting Web servers.
Load balancing
Distributing processing and communications activity evenly across a computer network so that no single device is overwhelmed. Load balancing is especially important for networks where it's difficult to predict the number of requests that will be issued to a server. Busy Web sites typically employ two or more Web servers in a load balancing scheme. If one server starts to get swamped, requests are forwarded to another server with more capacity. Load balancing can also refer to the communications channels themselves.

Rich data
A simultaneous combination of different data types (e.g. combination of textual and/or audio/and/or image and/or video data).
A device that forwards data packets from one local area network (LAN) or wide area network (WAN) to another. Based on routing tables and protocols, routers read the network address in each transmitted frame and make a decision on how to send it based on the most expedient route (traffic load, line costs, speed, or bad lines). Routers work at layer 3 in the protocol stack, whereas bridges and switches work at the layer 2. Most routers are specialized computers that are optimized for communications; however, router functions can also be implemented by adding routing software to a file server.
Secret-key encryption
A means to ensure user authorization. Secret-key encryption uses a shared key for both the encryption and decryption of transmitted material.
Server cluster

(Transmission Control Protocol/Internet Protocol) The suite of communications protocols used to connect hosts on the Internet. TCP/IP uses several protocols, the two main ones being TCP and IP. A communications protocol developed under contract from the U.S. Department of Defense to internetwork dissimilar systems. Invented by Vinton Cerf and Bob Kahn, this de facto UNIX standard is the protocol of the Internet and has become the global standard for communications. TCP provides transport functions, which ensures that the total amount of bytes sent is received correctly at the other end. IP provides the routing mechanism. TCP/IP is a routable protocol, which means that all messages contain not only the address of the destination station, but also the address of a destination network. This allows TCP/IP messages to be sent to multiple networks within an organization or around the world, hence its use in the Internet.

The organization's purpose is to develop open standards, so that the Web evolves in a single direction and not in competing directions. The W3C is the chief standards body for HTTP and HTML.
(Wide Area Information Server) A database on the Internet that contains indexes to documents that reside on the Internet. Using the Z39.50 query language, text files can be searched based on keywords. Information resources on the Internet are called "sources." A directory of WAIS servers and sources is available from Thinking Machines Corporation, Cambridge, MA.
(Wide area network) A communications network that covers a wide geographic area, such as state or country.
(Wireless Application Protocol) A standard for providing cellular phones, pagers and other handheld devices with secure access to e-mail and text-based Web pages. Introduced in, WAP provides a complete environment for wireless applications that includes a wireless counterpart of TCP/IP and a framework for telephony integration such as call control and phone book access. WAP features the Wireless Markup Language (WML). It also uses WMLScript, a compact JavaScript-like language that runs in limited memory.
Web browser
Application used to view Web pages.
Web server
A server that services requests for Web pages.
Wide Area Networks
A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs).
Wireless broadcasting
Broadcasting that uses high-frequency radio waves rather than wires.
(Wireless Markup Language) A tag-based language used in the Wireless Application Protocol (WAP). WML is an XML document type allowing standard XML and HTML tools to be used to develop WML applications.
(eXtensible Markup Language) An open standard for describing data from the W3C (World Wide Web Consortium). It is used for defining data elements on a Web page and business-to-business documents. It uses a similar tag structure as HTML; however, whereas HTML defines how elements are displayed, XML defines what those elements contain. HTML uses predefined tags, but XML allows tags to be defined. Thus, virtually any data items, such as product, sales rep and amount due, can be identified, allowing Web pages to function like database records. By providing a common method for identifying data, XML supports B2B transactions and is expected to become the dominant format for electronic data interchange.
Yield manager hub
Source operational inputs such as advertising, human resources, logistics and utilities, and work best where the demand and prices are more volatile and the goods or services are specialized.
