摘要
关系数据库的逻辑设计．由于其实现独立于现实世界，已成功地形式化了．而关系数据库的物理设计，由于其实现依赖于具体实现细节．很难用形式化加以描述．本文介绍一种在物理设计中融进需求分析的方法来驱动关系数据库的物理设计．
ogical relational database design,because of its implementation independent nature,bas been successfully formalized.Physical relational database design, because of its implementation dependent nature,has remained largely unformalized.This article introduces a method of requirement analysis for driving the process of phsical relational database design.
