Data Management System Based On Decision Support

The explosion type of the data increases in information age, technology changes with each passing day, the complicated decision environment and decision question have put forward higher request to DSS day by day. The appearance of representatives' decision support new technology, such as the data warehouse, online analytical processing and data mining, have offered the new ideas and methods for the administrative staff. They can obtain the decision information and knowledge from the data to make policy.The data management system based on decision support which this paper has put forward regards data as the systematic foundation and starting point. Through new technology of the data warehouse, on-line analytical processing and data mining etc., combining the system structure and relevant technology and method of data management of DSS, component developing approach and theory etc., we carried out the analysis and research on the data management system based on decision support in and the level model. Finally, we carried on relevant real examples analyzing through a DSS of country which our team bear.The paper includes the following parts of work1. The level model theory used for DSS designing and developing as to different DSS levels (use layer, task layer, logic layer and physics layer) have been analyzed and researched.2. The data management based on decision support, analyzing theory and technology have been researched. The paper is on the basis ofthe thing that the theory of DSS and data management are studied, have expounded the fact especially how to make use of warehouse technology of the data to realize structures half-and-none, organization and management of the structure data, and utilize and analyze and process and excavate the technology data to analyze and process with the data on-line, and develop certain research to working in coordination between them actually.3. Though software design of package and develop technology, the target -oriented analysis and developing instrument have been studied, and this technology been used to the coming when studies of the data management system based on decision support. And the design and development based on data management system package of decision support have been proposed and realized.
