| 摘 要： | 针对地震数据环境下如何进行信息资源建设、实现信息资源共享的问题,从面向对象的角度出发将UML与XML Schema结合起来,提出一种使用UML建模创建XML Schema元数据的方法。并通过XML Schema模式向关系模式的映射来存储XML元数据。文中对地震信息元数据XML Schema的建立进行了详细阐述,对UML如何转换XMLSchmea进行了深入研究。应用实例表明,基于XML Schema存储映射策略能够完整地将XML地震信息元数据存储于关系数据库中,有效地实现了关系模式下XML地震信息元数据的存取。

| Abstract: | Considering how to construct information resources and realize their sharing under earth data,the paper links UML and XML from object-oriented aspect and put forward an approach to use UML modeling to establish XML metadata that will be stored from XML model to mapping of relationship model.Details about establishment of XML Schema are discussed and how UML is changed to XML Schema.The cases show XML earthquake metadata can be stored in relationship data based on XML Schema and storage mapping strategy and that will realize access to XML earthquake metadata under relationship data model. |
