数据库设计对SQL Server数据库性能优化分析

Performance Optimization of SQL Server Database Based on Database Design

数据库系统是整个管理信息系统的基础与核心,其作用是将大量数据按照一定的规则组织在一起,方便准确,及时提供给用户使用。设计数据库看似简单,但是要实现数据库性能的最优化则非常困难,在数据库设计、应用程序结构、开发工具、接口选择及查询设计等方面都可优化。总体而言,提高数据库性能的方法有很多,其中改进数据库设计是有效的方法。影响SQL Server数据库性能优化的因素非常多,包含主观人为因素及客观因素等,其中数据库设计就是影响因素之一。笔者基于SQL Server数据库的结构特点,对数据库设计对SQL Server数据库性能优化的影响进行分析,主要从数据库逻辑、物理及事务日志文件等方面的设计进行分析,并尝试给出提升SQL Server数据库性能的设计策略。

The database system is the foundation and core of the whole management information system.Its function is to organize a large amount of data according to certain rules,which is convenient and accurate to provide users with time.The design of the database seems simple,but it is very difficult to achieve the optimization of database performance.It can be optimized in the database design,application structure,development tools,interface selection and query design,etc.In general,there are many ways to improve the performance of the database,in which the improvement of database design is an effective method.There are many factors that affect the performance optimization of SQL Server database,including subjective human factors and objective factors,among which the database design is one of the factors.Based on the structural characteristics of SQL Server database,the author analyzes the impact of database design on the performance optimization of SQL Server database.It mainly analyzes the design of database logic,physical and transaction log files,and tries to put forward the design strategy of improving the performance of SQL Server database.
