摘要
随着交通信息化应用的不断深入,数据交换和数据共享的需求越来越强烈,信息资源整合已成为交通信息化建设的核心内容之一.本文以北京市为例,分析了交通行业信息化存在的主要问题,并根据交通行业管理特点,提出了数据中心建设的总体框架.数据中心是一项复杂的系统工程,它涉及到网络、系统集成、信息安全、数据库、数据挖掘、标准规范等信息工程领域的各个方面.本文选取中心局域网、共享交换平台和中心数据库这三个核心系统,分别给出了中心局域网和共享交换平台的架构设计思路,探讨了在不同条件下数据交换和数据整合的几种方法.
With transportation informatization application being studied continually, the demand of data exchange and data share becomes more and more intense, and the information resource integration has become one of the main contents of transportation informatization. Taking Beijing as an example, the paper analyzes the existing problems in transportation industry informatization, and brings forward the framework of data center. Data center is a complicated systems engineering, and it comes down to network, system integration, information safety, database, data mining, standard specification, and so on. The paper chooses three core systems, which are center LAN, share platform and center database. Finally, the paper introduces framework design of center LAN and share platform, and discusses several methods of data exchange and data integration in different conditions.
