Business Process Integration Based On Web Service

Following with the improvement of social informationization, there are more communications and interactions needed among enterprise information systems. They should share data and cooperate with each other to complete business affairs. But for the historical and other reasons, enterprise information systems are mostly heterogeneous. So it is an essential problem to provide an efficient integration mechanism to realize application integration of heterogeneous systems, avoid enterprise "information islands" and optimize enterprise business processes.Business process integration consists of two aspects: the sharing of enterprise information resources and enterprise business process integration. It is the solution to enterprise business process flexibility in the system configuration and the implementation of synergy on the basis of the realization of the basic enterprise information system interoperability. In this paper, it is by the sharing of information resources from the enterprise and business process integration two angles to solve business process integration problems.1. In this paper, in addressing the issue of enterprise resource sharing,it is proposed based on the Web Service heterogeneous data model to address the issue of enterprise resource sharing.The model has some features: using data integration Web Service technology components and packaging applications, displaying data as a service, and achieving the exchange and sharing of data.2. In solving business process integration problem, the business process integration model is proposed based on Web Service.The business model is an integration middleware integration of the workflow technology and Web Service. Application Systems become Web Services by packaging interface and service registration centres by describing the services in the framework. The model is an intermediary for the services that routing information as well as the integration of business processes. Thereby, it is to maintain their independence and autonomy by enabling applications, while enhancing the flexibility of business processes.Using data integration and business integration model based on Web Service, the paper completes business process integration between enterprises. It meets the enterprise's operation mode changes by Eliminating of the Enterprise Information Island.
