中文摘要：

随着企业级应用的不断发展,企业越来越重视自己的数据信息,迫切需要解决企业内部之间的＂信息孤岛＂。针对这些问题,提出了一种基于Web服务数据集成框架的设计。通过研究异构关系数据库集成的常用方法以及XML与数据库之间的映射之间的方法,从而设计出一种数据集成框架,并运用J2EE和Web Services相关技术实现该框架。将该框架应用到某供电公司综合在线系统的项目中,通过对该系统的运行情况的分析,它可以有效解决该公司内部之间的＂信息孤岛＂问题,从而充分验证了该框架的可行性、有效性、实用性。

英文摘要：

With the growing development of enterprise applications,companies take more and more attention to their own data,and also need to address ＂Information-islands＂ between themselves urgently.To solve these problems,a design of Data Integration Framework Based on Web Services has been proposed.Through analyzing the method of Integration of Heterogeneous Relational Databases and the Mapping method between XML and database,a data integration framework which is achieved by J2EE and Web Services has been designed.Finally,the framework is applied to an online integrated system of a power company.Through the analysis of the system,it can effectively solve the ＂information island＂ problem of the company.It can prove that the framework is feasible,effective and practical.
