Decision Support Systems (DSS) are a class of computerized information system that supports business and organizational decision-making activities. A DSS is an interactive software-based system intended to help decision makers compile useful information from raw data, documents, personal knowledge, and/or business models to identify and solve problems and make decisions. With the advent of the Internet and distributed computing environments, organizations are recognizing the possibilities for distributed decision support in general and model sharing in particular. Through model sharing, organizations can leverage existing investment in decision models. . Recent developments in service-oriented architecture and web services for distributed computing may offer the necessary infrastructure for distributed decision support. The term service-oriented architecture refers to software architecture principles that rely on loosely coupled software services to support the requirements of the business processes and software users. In a SOA environment, resources on a network are made available as independent services that can be accessed without knowledge of their underlying platform and language implementation. The existence of UDDI server acts as a registry for web services modules and can be searched for specific web service for designated function.
