摘　　要：为了实现异构环境中数据集成的目标,提出了基于XML、B/S三层架构的企业异构数据库之间数据共享的实施方案,设计和实现了一个通用的异构数据集成系统。文章介绍了该系统的核心体系结构、工作流程和各模块的功能;阐述了XML文档模式的验证和提取、XML文档间的映射、XML文档模式和数据库关系模式之间的映射等关键模块的设计和实现;最后简要说明了实现系统所采用的相关Java技术。In order to realize the target of data integration in heterogeneous environment, the executive plan of data sharing among enterprises＇ heterogeneous databases based on XML and B/S three-ply structure is proposed, and a general heterogeneous data integration system is designed and realized. The kernel structure, working process and modules＇ functions of the system are introduced. The design and realization of key modules, such as the validation and extraction of XML schemas, the mapping of inter-XML document, the mapping between XML document schema and database relation schema, are elaborated. Finally, the relevant Java technologies used to realize the system are briefly illustrated.
