Research On Railway Information Sharing Platform Application Based On SOA

Service-Oriented Architecture (SOA) is an optimal solution for heterogeneous systems integration and application systems integration. It can make full use of existing resources to achieve cross-platform integration, increase reuse of function components to reduce development costs, accelerate deployment of new applications, reduce implementation risks and promote constant flow optimization. This paper reviews current actuality of railway information construction and existing problems of information sharing, try to introduce SOA to the field of railway information sharing. This paper brings forward new distributed information sharing platform structure scheme based on service-oriented architecture. It can cross boundaries of application systems, operation systems, and program language of various departments. Applications and data are released in the form of services packaging for users call, thus it form information services sharing platform based on SOA.This paper begins with the actuality investigation of railway information construction, and then analyzes existing problems of information sharing. After research on SOA and related technologies, puts forward services sharing concept of railway information sharing platform based on SOA .Through reuse of existing systems using Web services technology, this paper designs railway information sharing system framework based on SOA with reusability, loosely-coupled functions. It analyzes the overall architecture, application framework, service model and network topology frame of service-oriented railway information sharing platform in detail, and evaluates this project. Finally, this paper designs and implements freight-ticket information sharing system of"information sharing experimental system"of Railway Ministry project to validate the scheme proposed by this paper.
