摘要
数据流作为一种新的数据形态,不同于传统的静态数据,具有连续快速、短暂易逝和不可预测的特点,对其进行有效地分析和挖掘遇到了极大的挑战。介绍了数据流的基本概念、数据流模型、数据流处理模型和目前一些数据流管理系统,并对数据流技术及其挖掘算法进行归纳和分类论述。
Data stream is a new data form, which is continuous, fast, transitory and unpredictable, as compared to traditional staticdata.So it challenges to analyze and mine it effectively.The purpose of this paper is to review recent work in this field.The maincontents include data stream models, data stream processing models and current Data Stream Management System.Furthermore, datastream technology and its mining algorithm are also summarized comprehensively.
