Research On SCA Application In Railway Information Sharing Platform

Service-Oriented Architecture (SOA) is an optimal solution for heterogeneous systems integration and application systems integration. There are many manners to achieve SOA; SCA is specially designed for SOA, it is a new method and pattern of software development. It defines a simple model of Service Oriented, including constituting,assembling and deploying of the existing and newly-built service. 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 optimizationThis paper reviews current actuality of railway information construction and existing problems of information sharing, try to introduce SCA to the field of railway information sharing. This paper brings forward new distributed railway 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 Services Component.This paper begins with the actuality investigation of railway information construction, and then analyzes existing problems of railway information sharing. After research on SCA and related problems, puts forward railway information sharing platform technology framework. It analyzes the hierarchical architecture and overall architecture, of service-oriented railway information sharing platform in detail. Finally, this paper utilizes SCA architecture to validate the scheme proposed by this paper from Services Component constitution and railway service integration respectively.
