The Application Research Of Web Services In B2B Integration

In the Internet age changing with each passing day, the application based on Web has gone into families, and affect on all trades and fields. Especially, with the prevailing of e-commerce, more and more enterprises and organizations connect to network, and online transaction by B2C or B2B has become the inevitable trend of development of enterprises. In recent years, the market share by B2B has increased step by step. Although most enterprises have already established management information system (MIS), MIS of different enterprises run separately and enterprises continue to work in traditional communication and transaction manner. Therefore, it is quite likely to result in trade difficulty by lack of exact information share in time;many technologies have been applicated in the integration of B2B to resolve the crisis of information island. However, various integration technology and implementation have the advantages and disadvantages.With the development of Web Services technology which can solve the connection problem between Web application and desktop system, developers find that the interoperability of platform and the reuse of Web Services can offer a single sharing frame for business partners to effectively integrate among commercial process, application program,enterprise, cooperative partner, customer, etc. The appearance of Web Services have brought the bright prospect to the communication among business application programs constructed by different resources,thus enable them to cooperate each other and not be influenced by their implementation scheme.This thesis first discussed service standard and the technology which Web Services needed in design and realization, introduced the Web Services system structure, the protocol and the realization method with emphasis, including SOAP, WSDL, XML and UDDI and so on. Then this thesis analyzed the implementation tools of Web Services under some development environment such as Java and Delphi. In this foundation, the thesis Last designed a B2B integrative systemprototype based on Web Services, this prototype was applied in the application system integration and provided a good technical way to realize B2B integration.
