基于Web服务的分布式异构数据库集成研究
摘要:随着企业的快速发展和不断扩充,对企业内部新旧系统之间的数据、信息进行整合和共享,实现企业信息数据一体化日趋重要。但是,由于企业内部之间采用的系统以及数据库存在分布性和异构性,这必然会促进企业应用集成的发展。
本文首先介绍了分布式系统的概念、国内外发展现状,以及分布式系统的体系结构和特点。接着介绍了异构数据库集成的现状,以及异构数据相互集成的方法。然后对各种异构数据集成技术方案进行了分析,阐述了各自的优缺点。最后通过设计和开发一个基于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。

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 ing more and more ,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 it introduces the present situation of the integration of heterogeneous database,and each other of heterogeneous data integration 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,can 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.
Keywords: heterogeneous; distributed; Web Se
