摘　　要：随着网络的发展和企业信息化建设的推进,企业内部的"信息孤岛"问题日益突出。为更好地实现信息共享,在分析SDO架构的基础上,提出了一种基于SDO的虚拟视图多源数据集成框架。该系统集成框架利用XSD描述多重数据源信息,采用LAV方法映射全局视图,然后利用DAS实现对底层不同数据源的访问。文中详细介绍了该框架体系的构成及工作流程,并给出了具体实现过程。实例表明该方案有效地屏蔽了底层多源数据的差异性,较好地实现了多数据源的集成,解决了"信息孤岛"问题。With the network＇s development and the construction of enterprise information,the problem of information islands is increasingly prominent within the enterprise.In order to better share information,a multi-source data integration framework of virtual view based on SDO is proposed by analyzing the SDO architecture.The framework uses XSD to describe the multiple data source information,uses LAV mapping global view,and then uses DAS to realize the underlying access of the different data sources.Describe in detail the composition of the frame system and work flow,and give a concrete realization of the process.Examples show that the schema is effective in masking the underlying differences in multi-source data,and achieving the integration of multiple data sources to solve the information island problem.
