Enterprise Information System Integration Research Based On Work Flow And Web Service

While the enterprise competes internationally, the enterprise development faces the huge challenge which brings by the environmental variation. Faced with these challenges, the enterprise strives for the survival and development, unceasingly producing developmental strategy. The new management idea is proposed such as parallel project, dynamic alliance, supply chain. Not only is enterprise exterior supply chain system quite different, but also the database and enterprise interior system.The enterprise information system integration is an effective way to solve the enterprise information isolated island. It is already received more and more enterprises, integrated businessmen and the fundamental researchers' value. The fast development of electronic commerce, it proposed the new request for the enterprise information system integration. The concentrated expression should be dynamic in the enterprise information system integration, enabling an enterprise information system by the highest speed, the lowest cost.Our country's manufacture in the enterprise information system develops fast. How to use original information resource effectively causes the electronic commerce and ERP cooperatively, it will provide the good extension for enterprise among future system integration. The traditional EAI used to the best choice to solve the traditional manufacture's integration. But traditional system integration has high cost, and the realization is complex. It is not suit for integration under the new situation. Along with EAI( Enterprise Application Integration) and B2Bi (Business to Business integration), the people realize the B2Bi integration in the EAI foundation. The enterprise model is used to describe and understand enterprise operation process, analysis enterprise's performance and manage enterprise. Simultaneously it is an ideal tool to instruct enterprise information system constructing and implementation. The IT personnel may optimize the corresponding system using the service process of enterprise model definition, and carry on the corresponding system function; simultaneously the different service function entity according to its demand visits enterprise model, realizes integrated service operation and information sharing based on the model.This article first embarks from the analysis of enterprise information system integration. Summarizing the current enterprise information system integration lies in unable to satisfy integration dynamic and automatic. Then the article proposes one kind of method to describe based on the EPC, and optimizes enterprise operation process. Finally we use this model to instruct the enterprise information system integration which Web Service and Work Flow unifies.
