基于XML的北京轨道交通信息交换平台研究

Research on information exchange platform of Beijing Urban Transit based on XML

本文针对目前北京轨道交通各信息系统之间相互独立,数据资源共享困难的"信息孤岛"问题,提出了一种以XML作为中间交换格式,利用JMS作为消息通信工具的异构数据交换模型,最大限度地实现了应用系统接入交换平台的灵活性以及平台和应用系统的松耦合,对应用系统做到最小的侵入性。

This paper put forward a solution to the difficulties of sharing data resources among wuious application systems of Beijing Urban Transit, which used XML as the interchange format to exchange data among heterogeneous systems and JMS as exchange model of heterogeneous data for deliver of message. This solution achieved most flexibility of access to the exchange platform, made application systems and platform couple loosely, so, the application systems were invaded minimally.
