基于XML异构数据源融合系统的设计与实现

针对异构数据源分散存储给用户带来的不便，设计了一个基于XML异构数据源的数据融合系统。它基于B／S模式，分为应用层、数据层、通信层，采用XML相关技术解决了全局模式与数据源之间复杂的转换，以及异构环境下通信机制的不统一，同时系统采用了线程池技术，优化了系统的整体性能。在城市交通公用信息平台上的应用，表明系统能实时获取路面信息，满足了应用需求，达到了预期效果。

Design and Implementation of XML-based Data Sources Integration System

Storing the data in distributed nodes has been causing the users great inconvenience. In order to solve this problem, this paper design and implement a data-integration system based on the XML. This system adopts the B/S mode, and is mainly divides into three logic layers, which are application layer, data source layer, communication layer. The system applies the XML and related technologies to solve the complex conversion between global model and data sources, it also uses thread-pool technology to optimize the overall performance of the system. Practical application in urban integrated traffic information platform demonstrates that the system can capture real-time information of road surface, satisfies the application＇s requirements and reaches the respected effects.
