摘要
传统关系数据库系统通常用来存储没有时间概念的相对静止的数据,对于一些新的应用领域,信息是以数据序列的形式产生并且需要实时地、持续地进行处理,这就超出了传统系统的解决能力。数据流数据管理系统是面向流数据而设计的数据管理系统,它能有效地处理输入流数据并提供持续检索的功能。从整体上分析数据流管理系统的体系结构,重点讨论基于流数据的数据模型和流查询。
Usually we use traditional databases to store relatively static records without the notion of time for our applications. But information naturally occurs in the form of a sequence (stream) of data values and needs real-time, continuous processing which the old systems can't provide. Data Stream Management System(DSMS) is an dedicated designed environment which has the mechanism to manage the streaming data with the supporting of persistent queries. Delve into the architecture of DSMS with an emphasis on data models, continuous queries.
