Research and implementation of web service inheritance and interface web service

Web Service (WS) and SOA (Service-Oriented Ar-chitecture) are now widely used. The most important application of SOA is connecting various business systems that automate an enterprise's business processes. A new extension of Web Service definition and implementation-Inheritance of web service is pro-posed in this paper, just like the traditional inheriting mechanism of classes and interfaces in Object-oriented programming. It makes web service development and deployment more flexible, extendable and re-usable, and brings new thoughts and strengths to the implementation of SOA.
