The Research Of Enterprise Information System’s Model Based On SOA In Process Of BPR

With the development of economic globalization and informatization, competition between markets for enterprises is increasing. In order to maintain the competitive advantage and meet the individual needs of customers, the enterprise usually need to reengineer its own business process and provide quality products and services for clients. When the enterprise constructs new information system to reengineer old system, it usually lacks of unified planning for new system. It is difficult to adapt to the operation mode which focuses on customers. The enterprise usually develops information system by the way of scratch, so it can’t delivery business in time and drop satisfaction of users. And now more and more applications of system generate the difficulty of sharing and increase the maintenance cost. So the enterprise needs a new architecture model to construct its information system, the new architecture model must have flexibility to meet the needs of business innovation and adjustment of business process.The appearance of Service Oriented Architecture can help response the faster change of demand, it also shorten the time of delivery of the business and reduce the enterprise’s maintenance costs. This architecture has a number of peculiarities, for example, modular、service-oriented、standardization integration and flexibility. For the enterprises’existed problems in the business process reengineering at present, the application of SOA at the center of user and flow provides capacity of unified and flexible combination from integrating the interface、business process、service and information. The open architecture of SOA facilitates business cooperation between departments, and also it can support the new products and business and enhance the user experience.The article researches extensively business process reengineering、the theory of system and SOA. It describes the relationship of strategy of enterprise、management and technology, it also describe the interaction of inner elements from causality to structure the big system model oriented BPR. Based on these theories, the article establishes the model oriented BPR and based on SOA. According to the thought of hierarchical division, the research not only describes the structure from the technical level, but also presents that how strategy and management reflect the technical architecture to determine the different levels of vertical relationships. At last, take the system of investment project management of certain province’s mobile company for example, the article makes a concrete analysis of its corresponding structure model based on the thought of service oriented model and architecture. This architecture can construct the system of investment project management in fast、agile and low cost way.
