摘　　要：计算机网络的迅猛发展使企业内部数据交换越来越频繁,然而,系统实现技术及实现时间上的差异造成了在不同的信息系统中存在着大量异构数据。异构数据源的存在给实现不同信息系统间数据互访带来了很大的不便。为了解决异构数据源共享和部署集成平台过于复杂的问题,在充分调研国内外信息集成文献的基础上,基于XML和Web Service技术实现了一个新型的异构数据集成平台。该平台采用XML文件存储元数据,部署时无需新建数据库,实现了轻量级部署;将中介器和包装器发布成Web Service,支持多种集成平台客户端;该平台能够屏蔽网络、操作系统、各种关系型数据库、XML文件的异构性,支持企业集成历史遗留数据、发布信息,并具有高度灵活性、轻便性和可重用性。The rapid development of computer networks makes internal data exchange in corporation more and more frequently,however,the difference of system implementation technology and time make that a lot of heterogeneous data exist in different information systems.The existence of heterogeneous data sources is a big inconvenience for exchange the data between different information systems.In order to share the heterogeneous data sources and simplify the deployment of the integration platform,based on the research on the information integration in domestic and overseas,a novel heterogeneous data integration platform which adopts XML and Web Service was proposed in this paper.The novel platform which uses XML file storage the metadata achieves a lightweight deployment because it is not necessary to build the database;Publishing the mediator and wrapper into Web Service to support multiple integration platform client;The novel platform can shield the heterogeneity of network,operating system,a variety of relational databases and XML documents,support enterprise integrate the history data,release information,and have a high degree of flexibility,portability and reusability.
