摘要
针对异构数据源集成进行研究，给用户提供统一的查询接口，使其能在各个系统中查询信息。重点研究了基于虚拟视图法的异构系统集成设计方案，主要包括建立全局视图、局部视图、全局一局部视图关系映射以及异地异构数据融合方法。
This paper mainly researches on the integrations on heterogeneous systems, and provides to the user the uniform inquiry interfaces,through which users can get the desired information stored at different sites. Based on virtual view, the paper proposes an approach of heterogeneous data source integration, its main ideas include creating global views in the data exchange center, local views on the real application databases, establishing the mapping among the global views and local views, as well as realizing the integrations of heterogeneous data sources located at different sites.
