数据库行为代码的UML规范化设计

UML Normative Design of Database Behavior Code

UML作为一种强大的建模语言,有力地支持了应用设计和数据库设计。然而使用UML进行数据模型设计时,对数据库中的行为代码却缺乏有效的管理,不利于对其跟踪、扩展。提出基于规则的过程的观点,并阐述了如何对数据库行为代码进行规范化设计,同时使这类模型元素能在系统的迭代开发中得到有效跟踪和扩展。

As a powerful modeling language,UML gives support to the application design and database design.UML lacks,however,the sufficient management of behavior code in database,makes against tracing and extension,when using UML to design data model.This paper presents the PBR(Process Based on Rule), and expounds how to normatively design database behavior code and to make this type of model element be traced and extended in systems iterative development.
