Based On Web Services Dynamic E-commerce Model

Dynamic e-business emphasizes the interaction among programs and the need to replace traditional "inside-out"development by programmers with "outside-in" development by users. It will play the leading role in the next phase of the e-business. Web Services, which are based on XML, can encapsulate information, action, the representation of data and business process in the same way and they do not need to consider what kind of system and device the applied environment will use. By it, companies can pack their e-business as components and then integrate these components dynamically according to the business process. Thus, Web Services provide effective technical support to the implementation of dynamic e-business. This paper mainly makes an in-depth research on the dynamic e-business model, which is based on Web Services. First, describe the research actuality of dynamic e-business, summarize the background, concept, advantages and architecture of dynamic e-business and then put forward the research aim and content of this paper definitely. Second, introduce and analyze the Web Services architecture as a whole, describe the concept, features, class and implementing platform of Web Services and analyze the development foreground and the technical difficulties of Web Services according to the development actuality. Third, describe some pivotal technologies used to implement Web Services architecture: the first is XML which is the base technology, the second is the interface description language of services, the third is communication and message transferring of services, the fourth is the description, discovery and integration of services and the fifth is the integration of components in business process. Based on the theories and technologies of dynamic e-business, this paper introduces the design and implementation of a dynamic e-business platform and mainly describes the implementation of the Soft Integration Markup Language (SLML), the management of Web Services and business process and the interchange of XML documents. Finally, this paper summarizes the research on the dynamic e-business model which is based on Web Services, prospects the modification of the dynamic e-business platform and describes that the main research work in the next phase is to realize the interchange of XML documents by ebXML and the security and transaction of Web Services.
