计算机软件数据库设计的原则及问题分析

Discussion on the Principle and Problem Analysis of Computer Software Database Design

建立一个完整的数据库管理体系,为用户提供查询、分析、修改和处理等服务,是计算机软件数据库设计的终极目的。但是,数据库设计是一个非常复杂、系统的工作,在设计时,由于缺乏对数据库设计原理和方法的掌握,往往会导致数据库设计得不合理,从而影响数据库的性能。因此,每位软件开发者都必须清楚自己在数据库设计中遇到的问题,掌握其基本原理和方法,并按照有关原则和规范进行数据库的设计,从而有效提高系统的设计质量。文中以数据库设计为切入点,从计算机软件开发的实践出发,探讨了系统的设计原理及设计问题。

The ultimate goal of computer software database design is to establish a complete database management sys-tem and provide users with services such as query,analysis,modification and processing.However,database design is a.very complex and systematic work.Due to the lack of knowledge of database design principles and methods,database de-sign is often unreasonable,which affects the performance of the database.Therefore,every software developer must be clear about the problems encountered in the database design,master their basic principles and methods,and design the da-tabase according to relevant principles and specifications,so as to effctively improve the design quality of the system.This paper discusses the design principle and design problems of the system based on the database design and the practice of computer software development.
