SUMMARY OF THE ARTICLE
DECISION SUPPORT SYSTEMS AND WEB TECHNOLOGIES: A STATUS REPORT DECISION SUPPORT SYSTEMS, WORLD-WIDE WEB, DATA DRIVEN DSS,
MODEL-DRIVEN DSS, IMPLEMENTATION.

Introduction to DSS:
A decision support system (DSS) is a computer-based information system that supports business or organizational decision-making activities. DSSs serve the management, operations, and planning levels of an organization and help to make decisions, which may be rapidly changing and not easily specified in advance. Decision support systems can be either fully computerized, human or a combination of both. DSSs include knowledge-based systems. A properly designed DSS is an interactive software-based system intended to help decision makers compile useful information from a combination of raw data, documents, and personal knowledge, or business models to identify and solve problems and make decisions. World-Wide Web technologies have rapidly transformed the entire design, development and implementation process for all types of Decision Support Systems. In particular, Web technologies have provided a new media for sharing information about decision support and a new means of delivering decision support capabilities. For DSS developers, the big leap forward is to use the “Web as computer”. Modern decision support systems (DSS) provide managers a wide range of capabilities. Computerized systems support decision tasks like information gathering, model building, sensitivity analysis, collaboration, alternative evaluation and decision implementation. Also, decision support is increasingly integrated in business processes and DSS are used for ad hoc analyses. This paper reviews the current status of Decision Support Systems in the context of developments in Web technologies. The article contains brief historical reviews, discussions on implementations of decision support system and the major part of this article is ‘’State of Practice of DSS in 2001’’ HISTORY: Information Systems researchers and technologists have built and investigated computerized Decision Support Systems (DSS) for approximately 40 years. This article chronicles and explores the developments related to building and deploying DSS. The journey begins with building model-driven DSS in the late 1960s, theory developments in the 1970s, and implementation of financial planning systems, spreadsheet-based DSS and Group DSS in the early and mid 1980s. Data warehouses, Executive Information Systems, OLAP and Business Intelligence evolved in the late 1980s and early 1990s. Finally, the chronicle ends with knowledge-driven DSS and the implementation of Web-based DSS beginning in the mid-1990s. The field of computerized decision support is expanding to use new technologies and to create new applications..

Web-Based Decision Support Systems :
Power (1998b) defined a Web-Based Decision Support System as a computerized system that delivers decision support information or decision support tools to a manager or business analyst using a "thin-client" Web browser like Netscape Navigator or Internet Explorer. The computer server that is hosting the DSS application is linked to the user's computer by a network with the TCP/IP protocol. The idea of Web-enabled or Web-Based Decision Support Systems as services has been explored by various researchers and involves the concept of offering decision computation technologies as services on the Web. The recent popularity and widespread use of the World Wide Web and the Internet has been accompanied by the development of a variety of computing technologies that enable the realization of the “decision technologies as services” vision. Bhargava and Krishnan (1998) discussed the role of a series of enabling technologies in the context of Model-Driven DSS, covering technologies that enable...
