The Performance Optimization of Information Management System Database

With the development of information management system,as an important part of the management information system,database technology has been used widely.In order to ensure the information management systems operate normally,efficiently and safely,such issue as database performance optimization must be considered.Database performance optimization including reducing query response time,reduce the query need time and disk CPU I/O time,improve the throughput of database server.The mainly method includes database design specification optimization means,SQL statement optimization,improve the query plan etc.Through the study of database optimization method,and with a specific information management system database optimization example,this paper introduced the specific application of database optimization methods,which could do some efforts for the further development of database technology and information management system.
