| Abstract: | The drawbacks of traditional DSS is analyzed,and a DSS architecture structure based on data base is proposed. The structure includes model base, method base, knowledge base, data base and their management system, as well as OLAP, data mining unit and problem integrated processing unit. The functions of the system are studied,and the relationships and the key technologies of DSS based on the data warehouse are also investigated. |
