-
摘要: 介绍了一种新的数据库设计工具ERwin的编程设计方法,对概念数据建模、物理数据建模的原理进行了分析,在对"物资管理系统"的需求做了分析之后,建立了概念模型,然后使用概念模型生成物理模型,并在物理层让它们与SQL Server 2000建立了连接,最终在SQL Srever 2000中成功生成了数据库.Abstract: A new database design tool,ERwin has been discussed.The concept and physical data modeling methods at the different levels are introduced.After analysis of a practical application,a database has been successfully established by linking the physical model with SQL Server 2000.
