The Research On SOA Of Railway Passenger Information Sevice

Railway system has been growing together with the development of country and technology, the system set up in different periods which affected by the conditions of IT at that time. It can not take the problem of communicating and sharing with other systems into account. With the development of the times, more and more new requirements are proposed for the information management system. In order to meet these requirements, many systems need to update even to reconstruct, these may cause a series of practical problems, for example, resources can not be reused.SOA is a kind of loosely coupled software architecture. The main application of SOA technology is to realize the integration of information systems effectively. The method of SOA can make system encapsulate into several services, accelerate the speed of response for business needs, and finish the process of the reconstruction and integration for heterogeneous system by applying unified port.Firstly, by combining the existing ideas of SOA and related research achievements in domestic and foreign, this paper analyses the business composition and the key link for the current situation and business process of railway information system, sums up and describes the system function modules for railway information service. Second, according to the analysis conclusion of railway management information system, this paper introduces the basic concept and realization method of SOA, especially analyses the principles characteristics and service modeling method. It also introduces the main content of the SOMA method and the MSOAM method, and the methodology of oriented service modeling ideas. The latter parts of this paper make some researches on china railway information system, On the basis of research above, this paper establishes the modeling for china railway transportation system by using the modeling method ahead, illustrates the feasibility of the modeling method proposed in this paper. Finally, this paper realizes the modeling process of SOA by using Web Services technology.
