| 摘 要： | 在Web信息集成系统中，为解决数据源之间数据模型的异构性，提供一个有效的公共数据模型是一个常用的解决方法．在分析两种半结构化数据模型OEM和OIM的基础上，针对OEM模型表达XML文档存在的缺陷，将OIM的有向图结构与XML语言的相关特性相结合．提出了一种面向XML的公共数据模型XCDM．并补充了OIM对象代数的六种代数操作，XCDM充分考虑了XML语法表达的灵活性，可以为用户提供多级视图，完全符合公共数据模型的几点准则。

| Abstract: | In web information integration system, it was a general method to provide an efficient common data model (CDM) in order to integrate multi-data source with different data model. In this paper, a new data model called XCDM is presented based on two semi-structured data model: OEM and OIM. XCDM combinates the characteristics of XML with directed connected graphic structure of OIM, it can express XML documents flexibly and can provide view in different level for users and applications. Also two other object algebra operation is complemented besides OIM object algebra. XCDM is accorded with the rules of CDM. |
