Abstract
The decision support system is a software system that aims to facilitate and/or enhance the process of decision making activities at any organizational level. Decision support system has moved from the traditional role of supporting traditional business process into supporting intelligent decision making. Most of the proposed software architectures for decision support system are domain-specific software architecture. We have proposed simplified software architecture for decision support systems that is suitable as a generic software architectural style for decision support systems. We believe that the proposed software architectural style can work for many different domain problems for decision support systems.
