| 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, 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.The WEB system under the framework of SOA enables the user end gain the business logic through the citation of standardized Web Services interface; besides it helps the business logic of the system to be completely realized through either the service from third-party or service combination, thus improving the system developing efficiency substantially.This dissertation first introduces the concept, feature, merit, design principle and applied technology of SOA and goes deep into the discussion on the courses of Web service realization, publishing and binding. After the study of key technologies in the Web Service, we continued the research and used the SOA principles in the education platform by the Web Service technologies. It was a typical application in the system integration field. In this integration project, how to compartmentalize the service and manage the service were shown through analyzing the background of the project. At last we brought the scheme for realization. Also the paper gave a detailed design step for the service interfaces, which is very important for the application study of SOA. |
