Research On Service-oriented Architecture And Its Application

SOA has brought profound impact on the developing module of modern software, as it provides services for other application programs through mechanisms such as the publishing, the finding and the binding etc. of service. SOA possesses the sound features such as being loosened coupling, rough grain-size and retro-operative etc. Through the means of the design scheme adopting the SOA framework, the coupling among systems can be reduced to the maximum extent and the software reusing can be improved, therefore the remaining system can achieve a better integration to upgrade its flexibility and expandability.This article bases on the analysis of principle and implementation frameworks of SOA. Then the article aims at existing problems of the knowledge management system, which are heterogeneous and unshared on knowledge base. The article puts forward knowledge management system (KMS) which is based on WSRF. The work of this article shows as follows.Firstly, the article gives the concept, characteristics, basic principle and basic frame of SOA. Then it discusses the implement, published, binding of Web Service.Secondly, this article focused on analyzing implement framework of SOA. It provides general methods which are used for describing, accessing and managing resource for service requestor, service provider and the resource. Also, it integrates the network resource which is dynamic, distributed and heterogeneous. At the same time, it provides consistent, interoperable resource and service for user.Thirdly, the article puts forward knowledge management system based on WSRF (WKMA). This framework can fully utilize the existing network resources, and resources can be packaged into a grid service to use. Especially, it makes for expansion and sharing of KMS.Finally, the article gives the realization of the prototype system for WKMA. It provides solution for expansion and sharing of KMS. This prototype system has some practical value.
