Application Research Of XML Web Service Technology In The Development Of VET MIS

XSML Web Service, as a next generation oriented programming technology, is a network-based and distributed modularization, which can be described, issued, retrieved and transferred in the network system. It provides Web clients useful functions through standard Web protocol rather than SOAP protocol that is used in many other cases. XML Web Service can illustrate its interface in details, making it possible for clients to create client port application program and realize the communication between them. This illustration is generally covered in XML document, which is the describing language WSDL for XML Web Service. Once registered, potential clients will be able to retrieve the corresponding service through discovering, describing and integrating UDDI protocol and make use of the given functions. XML Web Service offers compact technique for the integration of application program, solving the problems of code reuse and being easy to dispose and maintain. Thus, it is widely applied in software development. This thesis, through the profound study of the application of this technology in software, systematically analyzed the structure and strategies of XML Web Service, concluding in giving some of the practical models on the basis of actual needs.As an important technology in the field of software engineering, software integration is to integrate different kinds of software utilized in any enterprise or organization, realizing intercommunication and information sharing between the systems XML Web Service has provided a new way of thinking for solving the above problems. First of all, the existing application systems need to be upgraded a B/S based configuration, with Web service enhanced. XML Web Service configuration will be adopted in new information systems design, consequently transferring the functions of Web Service in each information system.With the development of network and Web technology, interzone and interplatform distributive calculation becomes increasingly large-scaled and widely used. It turns to be the priority of enterprises' informationization to construct a distributive multiplayer system that is extendable, flexible, easy to manage, interplatform, of high multicomplextiy and security. XML Web Service, by means of adding a Web Service server between the operation object and data layer, can substantially realize the logical multiplayer in software system and physical distributive processing.Dynamic e-commerce is a new trend in e-commerce development. At this stage, the attention is focused on the program in the back-end of supply chain and the interaction between programs. XML Web Service will replace application to become the basic development tool on Web.Despite some of the application in software development, XML Web Service, as an entirely new technique of software development, is now facing a huge challenge. XML Web Service's software designing concept is still on the way to be recognized by software developers. In additions, its security specification needs to be bettered and its business operation mode to be established.
