An Improved Service Oriented Architecture to Enhance the Usability of Web Service in CERS

This paper is based on the "China Equipment and Education Resource System" (CERS) project, which aims at sharing large instruments and their related services. Web Service, which adopts service-oriented architecture, can provide loosely coupled, scalable and portable network modules for distributed applications. In this paper, an improved service oriented architecture to enhance the usability of the web services in CERS is proposed. More precisely, we add an operation protocol to the traditional Web Service architecture to give a more exact definition of the operation of web services. This new protocol makes the execution and composition of Web Service more convenient. A prototype system is implemented to validate the effectiveness of the modified architecture in promoting the service efficiency and improving the user experience. Our work may provide advice on services integration in some specific areas.
