Research And Implementation Of Enterprise Information Integration In Distributed Environment

With the development of information technology, distributed information systems inside the enterprises are increasingly large, systems are not compatible and information cannot communicate formed information isolated islands. There is an urgent need for the integration system, which can fast, efficient and accurate transmitted information as information isolated islands has seriously affected the development of enterprises. With the characteristics of loose coupling, independent of platform, SOA can solve this problem to eliminate the information isolated islands.This paper introduces the present situation of enterprise information integration, analysis the problems of Enterprise Information Integration exists, study the SOA, Enterprise Service Bus and Web Service and analysis the enterprise information integration at all levels by using the corresponding technology with examples.First of all, implement the data integration. By setting the standards form data and code, modeling the structured and unstructured data, building the theme database through the analysis of business objects, business line and subject field, and then realize the data exchange and sharing by using the data exchange platform and data sharing platform.Secondly, implement the functional integration. By using the unified interface provided by ESB to package the function in order to achieve the interaction between services. This paper represents the functional integration in aspect of the development, registration and searching of the services and design a function integration framework.Finally, implement the business process integration. This paper design a business process integration framework based on the BPEL by studying the business process execution language and analysis the development process of the business process combined with web service.
