摘要
概念模型设计是数据库设计过程最重要的环节,E-R模型因为具有简洁和清晰的优点成为目前主要的概念模型设计方法。但是,E-R模型不支持动态建模,缺乏灵活性,因而不能满足某些特殊部门的应用要求。因此,致力于支持数据库动态建模的框架系统研究,提出一种新的以面向对象方法为主要思想的动态建模框架。该方法给出一套能动态地对信息进行完整描述的概念模型,从而得到一种灵活、强大的数据库概念模型设计框架,实现数据库的动态建立。
The database concept model plays an important role in the process of database logical designing. E-R model is a effective model which is concise and clear recently, but now, it is not satisfaction with agility, which can' t build model dynamically. Therefore, it can' t satisfy application needs of special department. So a new dynamical modeling framework is presented using the object.oriented method. A suite of concept model is given which can completely describe the information. Therefore, a agile and powerful database concept design framework which can create database dynamically is achieved.
