基于XML的多维数据模型在交通信息平台中的应用

The Application of MML-based Multi-dimension Data Model in Transportation Information Platform

文章以管理线圈检测器获得的数据为例,研究了如何通过建立多维数据模型应用数据仓库技术管理海量交通数据。在此基础上,通过多维数据模型和XML文档间的相互映射,实现在不同ITS信息平台中的信息交换和集成。

This paper develops a multi-dimension data model for traffic data. Then, it introduces the data warehouse technology into the management of massive amount ITS data. Finally it points out that the XML document based on data warehouse plays an important role in ITS information interchange.
