学号： 常 州 大 学 毕业设计（论文） （2012届） 题 目 基于Web服务的分布式异构数据库集成二○基于Web服务的分布式异构数据库集成研究 WCF Data Service 的数据集成案例，在此案例中主要使用了基于XML的数据标准OData。 实践证明，基于EntityFramework以及DataService的分布式异构数据集成方案，可以很好的降低系统集成对客户端的限制，对于分布式异构数据集成具有较高的参考价值，该方案同样适用于手机等开发平台。 关键字：异构；分布式；Web服务；数据集成 Web service based on Distributed Heterogeneous Database Integration Research Abstract：With the rapid development of enterprises and expanding,of enterprise internal data between new and old system,information integration and sharing,realize enterprise information data integration are becoming more and more important.But,Because the enterprise interior is adopted between the system and the database is distributed and heterogeneous,this will promote the development of the enterprise application integration. This paper first introduced the concept of distributed systems,the domestic and foreign development present situation,and distributed system structure and characteristics.Then it introduces the present situation of the integration of heterogeneous database,and each other of heterogeneous data integration method.And then to all sorts of heterogeneous data integration technology solutions are analyzed,expounds the advantages and disadvantages of each. Finally through the design and development of a WCF Data Service based on the Data integration case,in this case the main use based on XML data OData standard. Practice proves,based on EntityFramework and DataService distributed heterogeneous data of integrated solutions，an be very good to reduce the system integration on client limit,for distributed heterogeneous data integration is of high reference value,the plan also apply to cell phone development platform.
