The Instance Investigation Of Developing Application Software System Based On Web Service

During the present day, distributed application, relax coupling and cross platform is the developmental trend of software development. And the development of software and Internet is high correlation; all the software makes more effort toward the orientation.Since traditional distributed application software model uses inherent model. The client accesses the services thru the close coupling-distributed protocol (DCOM, CORBA and RMI). But the service's flexibility and capability of cross-operation are limited by the close coupling architecture. Web service can solve all the problems. Web service is a new developing platform of distributed application software that can realize capability of cross-operation.In this thesis, a general Web-Service-Based model of application software developing method was designed, and explains the model with an idiographic application instance. The model contains advantages, such as cross-fields, cross-platform intelligence, based on Internet. This thesis first introduces the distributed computing models, the development of Internet, the basic characteristics of Web service, and then the basic theory and structure of a general Web-Service-Based model of application instance were analyzed together with the design idea and implementation.Finally, the thesis also gives an analysis of the limitations of the system model and its implementation, and the further research.
