现有的前兆数据分析处理系统多以C/S模式应用为主，本文提出一种基于Windows通信基础(WCF)的、B/S模式应用的实现技术途径，可以实现前兆数据的在线分析处理功能，并构建了原型实验程序SODEws。此方案实现的B/S应用既适用于各种计算机终端，也可用于支持Web浏览器的移动设备，并可实现基于云计算技术平台的部署。

 the existing precursory data analysis and processing systems had been dominated by using Client/Server (C/S) technical architecture by the time. A new technical method that is based on Windows Communication Foundation (WCF) and Browser/Server (B/S) structure is presented in this paper to realize online analytical and processing functions for Precursory Data. Moreover, a prototypical and experimental program named SODEws has been built, which is suitable for running not only on all kinds of computer terminals but also on mobile media with Web Browser. More importantly, this application can be successfully deployed in Cloud computing technical service platform.
