A Business Computing System Optimization Research on the Efficiency of Database Queries

This paper discussed the performance evaluation measurement and business computing system optimization based on some experiment researches on the efficiency of database queries. The relational database management system (RDBMS) is the most common data management system in recent years. The query efficiency affected the performance of the RDBMS. According to the experiments, several factors (the design of database, the difference between DBMSs, the selection of indexes) could be the reasons of the system performance. They should be considered when implementing the optimization.
