摘　　要：视图集成是异构数据源集成问题的关键技术之一。论文引进XML技术,利用其作为一种数据格式描述的元语言标准的优势,改进了已有视图集成方法,采用XQuery语言建立了真正意义上的虚拟的全局视图,为异构数据集成访问奠定了基础。View integration is one of pivotal technique in the integration application of heterogeneous data sources. XML has emerged as the standard of meta language representing data format, this paper improves on the existent methods of view integration by combining XML with them and builds a virtual global view with XQuery language, it lays a foundation for integrated query of heterogeneous data.
