摘要
大型数据库应用系统的性能优化是一项非常复杂的工作。为提高大型数据库应用系统的性能,简化大型数据库应用系统的性能优化工作,在设计阶段就充分估计和计算运行阶段的情况,重点对数据库进行优化设计。从数据库逻辑结构和物理结构两方面进行了数据库设计阶段的优化,应用系统的性能得到了明显改善。数据库优化设计是性能优化的基础,良好的库结构可以大大简化以后的优化工作。
Optimization of a macro-database application system is a quite complex job. To enhance the application system performance of a macro-database, simplify the optimizing job of the application system. In the designing process, the focus is put on optimizing design on the basis of good estimation and computation of the implementing condition. The performance optimization in the design process is carried out in the perspectives of the database logical structure and the physical one, respectively. The performance of the application system is greatly improved. Database optimization is the basis of performance optimization, good structure of a database. A good database structure can facilitate the optimization to a great extent.
