XML在污染源在线监控系统中的应用

摘要

Data transfer among various platform often occurs in pollution online monitoring system, and XML becomes one of the important methods of data tranfer for its good interactivity and being independent of platform. The application of XML in pollution online monitoring system introduced in this paper refers to the whole process of using XML document to transfer data. The low-layer sever based on VB packages and sends XML document using data picked up from SQL Server, and the high-layer sever based on ASP analyzes this XML document and storages received data into another SQL Server. It has been found that this application is stable and credibal, fully met the required function of the system.%污染源在线监控系统通常需要在各种平台之间进行数据传输,而XML具有交互性好、与平台无关等特性,使其成为数据传输的重要手段.该文介绍的XML在污染源在线监控系统中的应用,是在2个服务器之间利用XML进行数据传输的一个整体过程.低层服务器基于VB开发语言,将SQL Server数据库中的数据提取并封装为XML文档发送,高层服务器利用ASP开发实现,对接收到的XML文档解析提取数据存入SQL Server数据库.实践证明,使用该方法传输数据稳定可靠,同时也能很好地满足系统的功能要求.
