摘　　要：在企业信息化建设过程中形成的数据孤岛阻碍了企业信息化程度的进一步提高,研究异构数据集成模型,对于解决数据孤岛问题具有重要意义。通过应用XML技术构建数据集成中间实体,屏蔽各异构数据之间的差异,从而形成统一数据视图的方法,实现了一种异构数据集成新模型XDIM,并将其应用在青海大学综合信息服务平台中。该模型采用精简的算法,具有灵活高效的特点,能够有效解决多数据源环境下的异构数据集成问题。The model of heterogeneous data integration is researched to process of enterprise infomationization and blocks the further progress of resolve the ＂data island＂ which is formed in the enterprise infomationization. A XDIM model of heterogeneous data integration is achieved by constructing the middle data integration components to shield the defference among all the heterogeneous data and form a unified data view. It has been applied in the comprehensive information service platform of Qinghai University. With simple algorithm, the model possesses the flexibility and high-efficiency characteristics, and can effectivly solve the problem of heterogeneous data integration in the environment of multiple data source.
