Research On The Performance Optimization Of Data Warehouse

With the wide application and fast development of the computer network and the datahase technology, the management of enterprises has gone into a new era. But because the market is so changeful and ful 1 of competi tion, the management is urgent to obtain the useful information by a great deal of complex information in time, and then make correct and effective decision.Data Warehouse is a technical resolution aimed at the above problem, it is the core of the decision-making support system environment, which based on large-scale database.

It is used to support the decision of the management.In the application of data warehouse, the function problem of data warehouse seem to be is more and more important. The quality of data warehouse performance affect the usage of the data warehouse, and it is necessary to research on the Performance Optimization of Data Warehouse. In this thesis we mainly deal with the research on the performance optimization of data warehouse, including: the factor of the data warehouse performance, the performance optimization of data warehouse, the analysis and performance optimization of OLAP, at last, we use a example in the electric power system to show the practical application of ihe performance optimization in the data warehouse system.
