The Application Research Of Dynamic E-business System Structure And Corresponding Technology

E-business is a kind of economic activity that makes use of advanced information technology and communication measure based on the network platform. In general, an E-business system's structure in the enterprise is very complicated, because it is involved in many aspects of mutual business process. Traditionally, the integrating application on enterprise to enterprise is mainly assumed as the needed solving blue print by reengineering single enterprise software, but this type of tight associative solving blue print is poor in agility. When business requirement needs altering, it's very difficult to resolve these new problems only by refitting this kind of integrated configuration. It is very clear that the E-business system existed could not adapt for the new business pattern in the present.Dynamic E-business accelerates E-business's technology new development. Dynamic E-business provides such functions as business flow, dynamic extension and connection between clients and manufacturer systems for enterprises. By applying dynamic E-business, enterprises can search for business cooperation associates as soon as possible and establish corresponding business affairs relations immediately. So it can accelerate the integration of enterprises and create more profits for enterprises. WEB services and BPEL4WS provide effective support of technology for the implement of dynamic E-business.In this paper, based on both WEB services and PEL4WS the system structure of dynamic E-business, including its corresponding technology has been relatively deeply investigated.Firstly, E-business is briefly introduced, and the theory of dynamic E-business is summarized,including the generating background, concept, characteristic and business value of dynamic E-business. The goal and content of research are clearly put forward. Afterward, the technology of WEB services are recommended in the total, and its concept, characteristic together with basic service shed are also discussed, involving in such technologies as XML, SOAP, WSDL, UDDI in WEB services. In succession, the generating background and relative technique of BPEL4WS are introduced in detail.Secondly, based on having discussing of dynamic E-business, WEB services and BPEL4WS technology, an open and distributed dynamic E-business system structure are brought about. Moreover, the system structure of dynamic E-business is realized by applying technologies as follows: WEB services, BPEL4WS, J2EE, AXIS and so on.Finally, based on WEB services and PEL4WS, the research on the system structure of dynamic E-business is summarized. Furthermore, the further improvement of this research is prospected.
