| Along with the development of Internet, E-Commerce of B2B based on Internet develops too. Droved by the business benefits, each Enterprise built all kinds solutions of Business Portal and EAI base on its needs, most of them have the different of develop language, system platform, communicate protocol and data exchange formats. This make it is very difficult to integrate the new enterprise chain application and exchange data. New applications urgently need a kind of new Open Interoperable System Architecture. The Dynamic Integration Technologies based on Web Services fit the new demands, and it provides the support with next generation dynamic e-commerce.Web Services according to standard web protocol built a general component on the top of existing heterogeneous systems, which has nothing to do with system platform and develop language, and which greatly lowers the degree of coupling between the application systems and the parts of the same system, and which improves the expansibility and interoperability of application system. Dynamic Web Services makes Enterprise Application Platform can dynamically search and integrate Web Service during runtime, and it can dynamically update and resume Web Service when wrong happened. Dynamic Web Services Architecture cut down the cost of development, deploy and maintenance of system, and makes it is very easy to integrate heterogeneous systems, and improves the degree of open, interoperability, flexibility and adaptability.Web Services - Based Dynamic Integration System emphasis on the analysis of Web Services Architecture and its dynamic characteristic on the foundation of study of interoperability technologies. Firstly, it analyses the current technologies of application integration, and bring forward An Application Architecture of Web Services - Based Dynamic Integration. Secondly it studies the dynamic integration technologies of Web Services. At last it designs and analyses the Web Services Dynamic Integration System.
