| 摘 要： | 最近，人们已经广泛认识到：在某些新的应用领域中，把数据看作瞬时的数据流比看作持久的关系更为适合。本文首先分析了传统数据库管理系统处理数据流的局限性，然后分析了三个典型的数据流管理系统的基本实现技术，讨论了当前数据流管理技术的研究现状和今后的研究方向，最后，给出了一个数据流管理原型系统的体系结构。

| Abstract: | Recently a new class of data-intensive applications has become widely recognized: it is appropriate to treat high-speed time-changing data in some application as transient data streams rather than as persistent relations. This paper analyzes the limitation of the traditional Database Management System in aspect of dealing with data streams firstly, then the basic technology of three representative Data Stream Management Systems is mainly introduced. Fur- thermore, this paper reviews the recent studies for data stream techniques, including the research directions and re- search emphases of data stream techniques. Lastly the overview architecture of our Data Stream Manage Prototype System is given briefly. |
