UML模型向关系数据库的映射方法初探

The Primary Discussing of the Method of Mapping UML Model to Relationship Database

关系数据库的数据模型变得越来越复杂,用传统方法分析和描述变得越来越困难,在数据密集型的应用系统中,应用逻辑与数据存储存在差异,不利于开发人员的交流和开发过程的管理,这是文章考虑把对象技术引入关系数据库逻辑设计的出发点。统一建模语言UML是对象建模技术的发展结晶,可用于数据库的数据模型分析。通过技巧性的方法,可把UML模型映射到关系数据库,从而在数据库领域得到对象技术的诸多益处。

The data model of relationship database is becoming more and more complex,so more and more difficult to be analyzed and described using traditional method.Mean while,there are differences between application logic and the data store in data-dense applications,these go against the management of development process and the communication between developers.This is the beginning point for considering to introduce the object-oriented technology to the de-signing of the database logic.UML is the consequence of the development of the object-oriented modeling technology,and can be used to analyze the data model of database.Through skill method,people can map the UML model to the relationship database,and get the benefit from the object-oriented technology.
