针对城际间广域智能交通系统发展所面临的多源异构数据的问题,根据城际交通综合信息平台的功能和特点,提出了采用B/W/S(Browser/WebServer/DatabaseServer)结构的城际交通综合信息平台。其中,应用了虚拟数据仓库和可扩展标识语言(eXtensibleMarkupLanguage,XML)技术,将多类数据以XML的形式从各异构数据源中迁移到数据库服务器上,建立相应的虚拟数据仓库,以解决分布、异构环境下数据共享及利用的问题。利用XML实现数据共享的技术途径,进行实际应用开发。该平台具有良好的扩展性、开放性和灵活性。
According to the function and characteristics of inter-city traffic information platform, aiming at the problem of multi-source heterogeneous data in the inter-city wide area intelligent transportation system development, a B / W / S (Browser / WebServer / DatabaseServer) Inter-city traffic integrated information platform. Among them, the application of virtual data warehouse and extensible markup language (eXtensibleMarkupLanguage, XML) technology, a variety of data in the form of XML from heterogeneous data sources migrate to the database server, the establishment of the corresponding virtual data warehouse to solve the distribution , Heterogeneous data sharing and utilization issues. Using XML technology to achieve data sharing, practical application development. The platform has good scalability, openness and flexibility.
