摘要
为了有效解决网络环境中异构数据库数据集成问题,分析了异构数据库集成的现状,提出了一种基于XML技术的异构关系数据库数据集成模型。该模型由异构数据库层、集成中间件层、应用层3部分组成;阐述了该模型各个部分的功能,讨论了集成中间件层的实现;详细地介绍了数据库和XML之间相互映射规则,并给出了它们之间的具体转换过程。在集成中间件的基础上,设计了某信息管理服务系统软件,表明了该中间件的可行性。
To effectively solve the problem of heterogeneous database integration,the status of heterogeneous database integration is analyzed,and a XML-based heterogeneous relational database model is proposed.This model is divided into heterogeneous database layer,integration middleware layer and application layer three parts.The functions of the three parts in the model are depicted,and the implementations of the integrated middleware layer are discussed.The mapping rules between the database and XML are detailed,and the specific conversion process between them is given.Based on this integration middleware,a software of information management service is designed,which verify the feasibility of the middleware.
