Research And Design Of Distributed Enterprise Application Systerm Based On SOA

The traditional distribution applied system structure mostly are compose of independent tight coupling close systems by using various different technologies for the purpose of their own needs in the distribution applied fields of enterprise rank. However, one of shortcoming these systems are its restriction of further development and application in virtue of lacking compatibility and interoperability and reusability among the systems. Service-Oriented Architecture(SOA)is a non-reusable logic that urges enterprise to repetitive-use existing service resource by integrating each operation logic of system into service and form a system according to specific operation flow. Therefore, the subsistent problems of distribution applied system have been solved in this study.This paper presents firstly research background, purpose and significance of distribution applied system as well as the status of basic research in china and abroad. The conception and advantages of the SOA is introduced .By employing the SOA which is use in our design, concept of the Web Services and ESB which related to the theory of SOA techniques is carried out. Web Service is the method which can solve the reusable property of SOA software, and ESB can provide a platform for the integration between service provider and service applicant. Specifically, in view to a practice item, the data base of the liquid milk Branch of YILI Company is utilized as an example to describe its exploring background, structure of the system and design of the data sets. Meanwhile, the specific application of the Web service and the operating principle of the ESB were exposited respectively. Therefore, the purpose of design a client and service system has been carried out.In the aspect of system integration, Web service was applied to the creation, release and invocation of SOA, and ESB was applied to construct structure and achieve the disposition and application of service. In the aspect of system function, the integration of system database, main interface and system service port were obtained. A satisfied demonstration of functional modules interface between the client and service of YILI liquid milk enterprise department production management was carried out in the finally section of this paper.According to the practical application, the SOA structure model can provide good expansibility, flexibility and transplantation. Depending on this model, the distribution applied system with more excellent function and applicability can be constructed.The developed system introduced in this paper has passed the tests and achieve desired results. It has been used in practices.
