| 摘 要： | 分析了目前计算机网络中异构数据集成的现状和存在的问题，提出了一种基于XML异构数据集成的公共数据模型CDM，通过在全局模式和中间模式、中间模式和局部模式之间建立映射机制，将全局模式、中间输出模式和局部模式联系起来，较好的解决了各异构数据源在集成过程中数据的重构和格式差异问题．

| Abstract: | This paper analyses the current situation and problems of heterogeneous data integration in computer network, a CDM model of heterogeneous data integration based on XML is given. In this model, through the establishment of mapping mechanism between the global schema and intermediate schema, intermediate schema and local schema, it can link the global schema, intermediate output schema and local schema, and it has solved the problem of data rebuilding and format difference in the process of heterogeneous data source integrating. |
