Based On The Power Of Data Warehousing, Decision Support System

Although the DSS (Decision Support System) has developed for more than 20 years, the research and development of the DSS has stayed in theory, it has not been put into practice, Because it is difficult to explore the traditional DSS based on the model base. The rising of the DW (Data Warehouse) technology and the OLAP (on-line analytical processing), DM (Data Mining) technology provides a new way for the development of DSS.Electric power industry is entering the stage of rapid development. The industry's service concept is changing from planning power distribution to exploring market, from administration to marketing and serving. This new mechanism follows the direction of the market, centers internally on sales and management while externally on client service. It requires the administrators and decision makers of an enterprise to make quick and scientific decision according to changing environment.With the deepening of the system reform of electric power, and the acceleration of the market-oriented paces of the power supply enterprise, it seems very important to make the marketing management strategy adapting for market. Power-Supply DSS can collect all kinds of scattering detailed data source, and make Data Warehouse (DW) faced to all kinds of topics, at the same time, dug the instinct law of the task and the quantity information accessed impossibly by manpower, and then based on these quantity information, make more scientific Power-Supply Marketing DSS. According to Jinan electric power company' s demand, we set up the Power-Supply DSS based on the theory of the DW and DSS.At first,this article analyzes the research background meaning of this subject,and introduces the domestic and international current situations of the development of DW and DSS. Then it describes the relevant theory knowledge of the data warehouse , the setting-up of data warehouse model separately. At last, combining the Power-Supply DSS project of Jinan electric power company we have participated in, this article expounded the fact in detail how to make use of the technology of the warehouse data to construct an Power-Supply DSS, and how to make use of data warehouse of decision to carry on the data analysis, meeting the demands of DSS. At the end of article, it Summarizes the work we have made in this project. Then it looks forward to development in the future of the...
