摘要
持久化框架较好地解决了关系型数据库的对象持久化问题,对象关系映射是持久化框架的核心内容。参考MOF标准,本文设计了面向对象和面向关系的元数据模型,在分析属性映射和关系映射的基础上,介绍了基于元数据的对象关系映射,最后讨论了利用XML技术的实现。
The persistence framework solves the problem of object persistence in relational databases. Object rela- tional mapping is the core of persistence framework. This paper, which refers to the standard of MOF, has designed the metadata model of object-oriented and relational-oriented. Based on the property mapping and relationship map- ping, we interpret the Object-Relational mapping using metadata. Finally, we discuss the implementation of the XML-based technology.
