摘要
随着数据库应用从以事务处理为中心逐渐向以分析处理为中心转化,以数据仓库、联机分析和数据挖掘为中心的基于数据库的分析技术成为近几年来数据库界研究的热点。经过近十年的研究与应用,已经产生了很多的研究成果,建立了较扎实的理论基础,目前正在向与应用领域紧密结合(如流数据),对现有技术进一步改造方面发展。本文对近两年这几个方向上的研究成果进行了总结。
In the past most of database applications are transaction oriented. But today more and more applications are analysis oriented. That the reason so many researchers worked on data warehouse, OLAP and data mining. After near ten years hard work, the theory of these techniques has been studied. The base of further research has been formed. Now more and more work is around the method to solve the problems met in real application such as stream data. How to improve the technique used today are also hot topic today. In this paper we make a survey of these techniques.
