摘　　要：数据流是近年来出现的一种新的数据形式,这类数据的特点是以连续的、实时的、无限的形式出现.针对传统的数据库的查询处理技术已经不适合数据流的问题,研究了数据流管理系统TelegraphCQ的开放源码,在此基础上详细阐述了TelegraphCQ的系统结构、TelegraphCQ的数据管理方案和查询处理技术,同时给出了建立TelegraphCQ的详细步骤及其使用方法.In recent years , there has been a dramatic growth of interest on a new data form-data streams which are continuous, real-time, unbounded. Conventional database techniques for query processing, which were developed under the assumption of a far more static and predictable computational environment, will be inappropriate to data streams. TelegraphCQ, a data stream management system, is focused on meeting the challenges that arise in handling large streams of continuous queries over high-volume, highly-variable data streams. In this paper, by studying on the source code of TelegraphCQ system, the authors expatiate on the architecture of TelegraphCQ system, the data management strategy and query processing techniques of TelegraphCQ system, and give the steps to install and the methods to use TelegraphCQ.
