摘　　要：网络提供了一个无限的、变化的信息源,使得数据库由传统的静态存储变成了动态的存储,数据变成了流数据,查询变成了连续查询。为了有一个完善的系统来处理大量的数据及查询,提出了一个流查询处理方案,同时满足普通用户和高级用户(有计算机语言基础),并从几个重要的指标来阐述了如何提高查询效率,减少了系统瓶颈,并在原型系统中得到了验证。Internet has bought us an infinite, variational information source, which leads to change the database from traditional static store to active store and to change data to streaming data and to change query to continuous query. A streaming-process project is put forward which adapts to common users and advanced users (know well in computer language) at the same time for having a perfect system to process amount of data and queries this expatiatiates how to improve efficiency of query and reduces systemic bottleneck and is validated in prototype system.
