Study on E-business logistics system based on SOA

SOA is a new kind of architecture design for system development. It can solve heterogeneous problem by decomposing software services module and integrating service module. Traditional logistics information system has poor scalability and reusability, it is easy to form information islands. E-business logistics information system based SOA provide an ideal framework for design and implementation of logistics information system. In this paper we first discusses the framework of E-business logistics system based SOA, the whole system is composed by basic network layer, logistics resources layer, services support layer, business integration layer and E-business layer from the top to the bottom.Confirm that services support layer is crucial in the framework. We mainly consider the construction of service model when we study the service support layer,and gives the idea of service model tree. Proposed service modeling method by core of the data manipulation, determine the service model´s core technology, data entities and data manipulation correlation matrix. On the basis of analysis and design of framework, discusse the interface problems of the interface standard, granularity, and loosely coupled. Finally, discusse the key techniques in SOA.
