Research and Implementation of Data Warehouse and Data Mining in Decision Support Systems

DSS (Decision Support System) is to support decision makers and improve the decision-making process,which is much promising in CIMS,virtual enterprise,medical diagnosis and so on.Some techniques related to DSS are introduced,such as data warehouse,knowledge discovery in database and distributed object.Then a kind of integrated IDSS development environment is put forward, which combines the traditional IDSS with the data warehouse, applies a special model named data mining model to knowledge discovery in database and adopts distributed object technique in implementation. Finally,the design and the implementation of the data warehouse and knowledge discovery in database are introduced.
