基于虚拟数据仓库的第四方物流信息平台

Fourth party logistics information platform based on virtual data warehouse

针对第四方物流信息系统建设中存在的多源异构数据问题,提出了基于虚拟数据仓库和XML技术,采用B/W/S(Browser/Web Server/Database Server)结构的第四方物流信息平台,将多类数据以XML的形式从各多源异构数据源中迁移到数据库服务器上,以解决分布、异构环境下数据共享及利用的问题。对其中的虚拟数据仓库和XML格式转换器技术做了详细说明,并结合实例进一步说明了转换器的具体实现算法。

The fourth party logistics information platform （FPLIP） is designed to provide a broad spectrum of operational data from complex and distributing data sources strategically placed which as the key input to the fourth party logistics information system （FPLIS）. A new architecture develops for the FPLIP based on virtual data warehouse and XML. The FPLIP architecture is presented in which the virtual data warehouse receives a wide range of data from multiple and distributing sources and the functions and advantages of the virtual data warehouse are analyzed based on the complex and distributing features of the FPLIP, the virtual data warehouse and XML format transform method even the XML format transform algorithm through an example.
