The Application And Research Of Web Services In EGO365 Website

Now the concept of Web Services is very popular. The reason why this concept can be the hot point of E-business is that it can solve a lot of difficulties during the process of developing E-business. Web Services transfrom XML data, and the XML data is self-description data. That means the partners of E-business need not to negotiate the data structure before processing data. Dynamic E-business is the advanced stage of E-business development. The environment of dynamic business may change frequently .The E-business system based on Web Services can fulfill the needs. The relationships between services can be built or broken up according the changes. In the distribution enviroment, DCOM and CORBA were often used. But they use private protocal and the encoding of data is quite complex. On the contrary, the data encoding of Web Services is much easier. As the development of technology, SO (Service Oriented) will finally substitute 00 (Object Oriented). Considered all of the factors, Web Services will become the hot point of E-business.This paper is based on the scientific research project--"new database technology based on web services", a sub project of national "863" high technology research development plan. And it focuses on the research and development of E-business Oriented Web Services that are applied in EGO365 E-business system.First, we expatiate on the architecture, the stack of protocols, the description and discovery of Web Services. And it is also introduced that the key technology during development of Web Services, the SOAP protocal. Several important elements of SOAP are introduced that including SOAP Envelope, SOAP Encoding, SOAP RPC representation and so on.After the presentation of the related technology, we mainly describe on a digital shop system, which applies Web Services. The system takes advantage of Web Services to complete integration with other enterprise application, reduce the cost and duration of development, and increase the opportunity of component reusing.The design of the system consists of the following three parts: the design of a B2C web application of the digital shop, the design of Web Services provided by EGO365 system, and integration between digital shop and EGO365 system.At last, the whole paper is summarized. The digital shop system applies Web Services technology, and it has fine cross-platform operation ability and can be well used in the system integration of E-business.
