摘要
关系模型是当前成熟的、普遍应用的数据库设计技术,随着面向对象技术的迅猛发展,UML对建模符号进行了统一,在面向对象方法作出了重要贡献,将UML静态设计模型与关系数据库设计相结合,提出一套完整的对象-关系映射方法,并进行相应规范化,满足3NF,在创建数据库方面具有很大优越性。
The relational model is the popular and mature database technology. The unified sign named as UML is created with the development of Object Oriented technology,and has made important contribution on OO method. A set of mapping method about database design named object-relationship is presented, which is not only formalized to 3NF but also has superiority in the field of establishing and maintaining database.
