OLAP数据挖掘引擎算法的设计与实现

Designing and implementing algorithms of OLAP-based data mining engine

基于OLAP的数据挖掘,是数据挖掘的一个新的发展方向。对于如何把OLAP(联机分析处理技术)和DM(数据挖掘)统一起来,从而在数据库或数据仓库的不同层次进行挖掘,提出了OLAP数据挖掘系统的结构。通过研究数据挖掘方法和OLAP操作的特点,以及数据立方的构建和物化,对传统的DM算法进行了改进,设计并实现了更能适应OLAP数据挖掘引擎的算法。

OLAP-based data mining is a new direction of DM. Considering unionizing OLAP technology with DM technology to do data mining at different levels of database or data warehouse, a framework of OLAP-based data mining system is designed. By studying the methods of data mining and OLAP operation, and the creation and materialization of data cube and by improving traditional DM algorithms, the algorithms of OLAP mining engine is put forward and implemented.
