摘　　要：铁路数据中心是企业级一致的、面向主题的、跨专业的、具有多重粒度级别的、多层次的可共享的铁路基础数据和业务数据平台,将为铁路部门的数据服务、信息处理和各层次决策分析提供低成本的、有效的企业级、分布式数据支持。针对铁路数据中心的应用功能类别和数据特点,提出一种以面向服务体系架构(SOA)为基础的数据展示方案。该方案通过松耦合的组件结构设计,能合理为各种应用提供统一的跨层次的数据获取和展示接口,也能通过现有功能封装和接口定义,达到充分利用现有信息系统的功能和节省基础投资的目的。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.
