The Application Research Of Enterprise Information System Based On SOA

The Service-Oriented Architecture (SOA, Service-Oriented Architecture) is a new software architecture, and the emergence and development of SOA for enterprise application integration provides a solution.Its core concept is service. Compared with the traditional development model, its greatest advantage is loose coupling,platform independence,solving the interoperation problems among heterogeneous systems and flexible to future needs. Thus,on the purpose of building enterprise systems based on SOA, the elements of service-oriented architecture, the main implementation technology, service-oriented analysis and implementation of enterprise systems were studied.This paper introduces related implementation technologies of SOA,as well as the J2EE support to SOA.The paper also discusses design principles, design patterns and the functional role of ESB in SOA.Based on a multi-layer structure based on ESB,a SOA framework is proposed by service analysis. And a enterprise application integration framework which completely based on open source software was also built after the study in mainstream open-source framework at present.This framework uses light Mule ESB as the base of the integration service and Xfire as the implementation of Web Service.It fully uses the configurable strategies to achieve various system hot-swappable components. Web Service interface is provided for communication among the other systems. The integrated effect of this architecture is very nice.Finally,based on the multi-tier architecture of SOA and lightweight enterprise application integration development platform,It implemented flexible communication among three prototypes systems which are product management system,sales management systems and customer management systems. In the same time,it provides a perfect scalability to meet the future needs. The system architecture so flexible as to improve the availability of enterprise resources.
