摘要
因为大型数据库与小型数据库在数据量上有了质的突变,若要使系统达到最优化的性能并不是一件容易的事。如果设计的数据库模型不够合理,不仅会增加客户端和服务器端程序的编程和维护的难度,而且会影响系统实际运行的性能。文章从大型数据库设计与应用的不同阶段来分析比较数据库性能优化的相关技巧,给出了一些具体的优化方法。
Compared with a small database, the data in a large database have a qualitative mutation, and it is not easy for the system to achieve optimum performance. If a designed database model is not reasonable enough, it will not only increase the difficulty in programming and maintaining the client and server, but also affect the practical running performance of the system. The related techniques of optimizing database performance are analyzed and compared from the different stages of large database design and application, and some specific optimization methods are given.
