| 摘 要： | 论文主要探讨以UML对象类图作为数据库建模的方法：在UML的对象类中得到关系模式的键,把关联的多重性分配到关系模式中去,把泛化（继承）联系转换为关系模式,把行为（操作）转换为触发器和存储过程;从而将UML与关系数据库技术相结合,方便数据库的设计。

| Abstract: | This paper introduces the database modeling with the class diagram. The methods include the getting of the primary key of the relation schema from the UML class diagram, the assignment of the multiplicity of association to relation schema, the transformation of the generalized association（Inheritance） into relation schema, and the transformation of the operations into triggers and stored procedures. The combination of the UML with the relational database facilitates the design of the relational database. |
