Web-based B2b E-commerce Services, Key Technology Research And Design,

With further combination of enterprise and IT, the value of E-Commerce is becoming obvious. Efficient and low-cost E-Commerce brings a new growth point of economy, with broad prospect of development. It is the focus on competition among many countries and companies, and is also the main content of our country's construction of informationization. To meet the rapid changing requirement of the market, enterprises must build new business models by flexible IT architecture, and dynamic union among enterprises on the Internet through boundaries of enterprises. How to carry out business to business integration and promote the combination of fund flow, goods flow and information flow, is the chief problem of B2B.Service Oriented Architecture is a milestone marks the progress of distributed system and software integration. Service that is an autonomic open platform-independent network component can make the distributed application get better reusability flexibility and growth. Loosely coupled Web Service that is the major implementation technique of Service Oriented Architecture provides distributed heterogeneous enterprise application with validated integration. Enterprise application based on Web Service not only can protect investment and reuse legacy system fully, but also support enterprise's agility on demand and advanced service outsourcing.The key technologies vital to E-Commerce development are E-Commerce system's performance and security. Business progress among enterprises is the thief advantage of B2B Based on Web Service. The thesis puts forward an idea of modeling service composition. It is that firstly encapsulate the whole business to a composite service, then split the service into atomic services step by step, lastly composite the component services based on work flow. The thesis takes a typical business process in B2B as a research instance and has designed a service orchestration and choreography scheme. It profits the combination of fund flow, goods flow and information flow. To construct a trustworthy E-Commerce environment on technology, the thesis taking advantage of current security mechanisms has designed a security solution of B2B based on Web Service. It has built an end to end massage security, and ensures transaction safely by transforming normal SOAP massages into safe ones.
