The research of DSS (Decision Support Systems), mainly in the last twenty years resulted in the appearance of new technologies and concepts regarding storing, processing and analyzing data and information necessary for the decision-making process. Consequently in the DSS landscape, the technology of ”Data Warehouse”, OLAP (“On-Line Analytical Processing”) applications, “Data Mining” techniques and artificial intelligence technologies (expert systems and intelligent agents) are present. In this respect DSS development is a complex process, which needs an adequate methodology or framework, able to manage different tools and platforms in order to fulfill management requirements. The DSS development process should be treated as a unified and iterative set of activities and operations. The new tools based on Unified Process (UP) methodology and UML (Unified Modeling Language) seem to be appropriate for DSS development using prototyping and RAD (Rapid Application evelopment) techniques. This paper presents state-of-the-art DSS development methodology and framework using Unified Process, UML and DSS-UNIDEF.
