Application And Study Of Web Service-Based Dynamic E-Business System

With the rapid development of e-business, both internal and external enterprises need more interactive requirements. However, the traditional data exchange approaches, e. g. HTTP or FTP, can' t meet interactive requirements in business process, because all kinds of data based on different software and hardware environments, and most of them distributed in different networks. The dynamic e-business is design to solve problems above. Web Service is the key point to implement dynamic e-business, and it provides distributed computing. The platform and language independence attributes of Web Service could realize interoperation between platforms of different applications, and integrate enterprise systems successfully.We introduce the related work and the significance of the dynamic e-business, and present the relationship between dynamic e-business and Web Service. Then, this thesis presents the technologies of description, publishing, and search of Web Service. This thesis also presents key technologies including how to use XML to describe data object, and the encrypt technology based on WS-Security and XML digital signature. This thesis also presents framework design technology based on Struts, EJB and XML.In the applied case study of our work, we analyze a case of e-business running for a medical company. Using Web Service and XML, we successfully implement main functions of iERP e-business system, including storehouse query, product quote, and online-order service.At last, we make a conclusion, summarize the main research activities and discuss the future work.
