Data presentation scheme for Railway Data Center based on SOA

Railway data center was an enterprise consistent,subject-oriented,business-across,multi-granularity,multi-level,and sharable data platform of railway fundamental data and business transaction data.It would provide enterprise wide and distributed data support for data service,information processing,and different levels of decision support of railway system in a low cost and effective manner.In this paper,according to the categories of front-end applications and data characteristics of railway data center,it was proposed a data presentation scheme based on Service-Oriented Architecture(SOA).Based on a loosely coupled components design,the scheme could provide uniform cross-level data acquisition and representation interfaces for various applications reasonably.Meanwhile,the scheme could make full use of functions of the Existing Information Systems and save infrastructure investment through packaging the existing functions and defining interfaces.
