摘　　要：针对数据库存在的异构问题和集成的需要,提出一种基于XML中间件技术的异构数据库集成模型,该模型由异构数据源层、中间件层和应用层组成。详细阐述中间层的实现流程和实现的相关技术。设计并开发流域水环境异构数据库集成中间件。数据集成实验证明:该模型具有可行性、扩展性和透明性等特点。Aiming at the existing problem of heterogeneous database and needs of integration, it presents a method based on XML middleware of heterogeneous database integration model,which consists of hetero- geneous data source layer, intermediate layer and application layer. The middle layer of the implementa- tion process and related realization technology are given, as well as the design and development of a river basin water environment of heterogeneous database integration middleware. Data integration experiment indicates the model has been equipped with feasibility, expansibility and transparency and so on.
