Model-Driven DSS are usually focused on modeling aspecific decision or a set of related decisions.Decision Support Systems should be defined as a broad category of analytical management information systems. DSS provide managers more control oftheir data,access to analytical tools, and capabilities for consulting and interacting with a distributed group of staff. An enterprise- wide Decision Support System is linked to a large data warehouse and serves many managers within one company. Also, aDSS is defined as an interactive system in a networked environmentthat helps a targeted group of managers make decisions. The primary focus in the followingdiscussion is on various types of Decision Support Systems.The term MIS will be used sparingly and usually it will broadly refer to any information system that assists or supports managers in their various tasks.5.3. Decision Support versus Transaction Processing SystemsDevelopment of Decision Support Systems is one of the rapidly changing frontiersin theapplication of computers in organizations. One reason we study DSS is tounderstand how theydiffer from other systems. We have successfully learnt how to implement computer-based Transaction Processing Systems (TPS), but knowledgeof building these operational systems isnot adequate to create effective DecisionSupport Systems. So if DSS are to be successfullydesigned, developed andimplemented, then both managers and many MIS professionals need amoresophisticated technical and philosophical understanding of Decision SupportSystems.Technology is creating new decision support capabilities, but much learning anddiscussion needsto occur to successfully exploit the technological possibilities. Decision Support Systems differ in many ways from operational TransactionProcessing or Online Transaction Processing Systems. For example, a popular system that has been widely implemented is called Enterprise Resource Planning
