摘要
分析了采用元数据库统一管理元数据的方法,总结了构建J2EE平台的元数据库4点要求。并且采用MOF和XMI标准,结合开源项目EMF,实现了基于J2EE的平台的元数据库,该元数据库可以对外提供查询、分布和更新元数据等服务,最后结合Hibernate实现从Model到关系数据库的映射来阐述元数据库的作用。
The methods of utilizing metadata repository to manage metadata in a universal way are analyzed. Four requires of constructing J2EE metadata repository are summarized. And following MOF and XMI standards, the metadata repository based on open source project EMF in J2EE platform is implemented. The metadata repository can provide services of query, publish, and update metadata etc. Finally, the function of metadata repository service is illuminated with Hibernate.
