摘要
利用XML技术对异构数据库的集成方法及其实现进行研究。针对目前信息系统综合集成中对于异构数据库的集成需求,提出利用XML Schema具体实现数据转换与集成功能,在关系数据库的数据表定义和XML数据文件之间建立映射机制,实现数据库数据与XML文件中数据的双向交换。实验证明,该方法可以较好地提高异构数据集成的效率,节省信息集成的成本,实现对现有数据库的充分利用。
Based on XML technology, the heterogeneous database integration method and its implementation are researched. For cur- rent information system for comprehensive integration of heterogeneous database integration needs, the use of XML Schema implementation data conversion and integration capabilities are proposed, data in a relational database table definitions and the mapping between XML data file mechanism to achieve database data and XML files bidirectional data exchange. Experimental results show that this method can better im- prove the efficiency of heterogeneous data integration, information integration cost savings, to achieve full utilization of existing databases.
