摘要
提高联机分析处理(OLAP)的响应速度是数据仓库研究的核心问题之一。文中根据多维数据模型的结构特点以及OLAP需求提出了一种变粒度存储策略。实验表明该策略能有效地减少存储空间,提高OLAP响应速度。
To improve OLAP's response time is a key problem in the study area of data warehouse. According to the structural characteristic of multidimensional data model and OLAP's needs, a various granularity storage method has been presented to store historical data. Test shows this method can efficiently decrease the storage space and improve OLAP's response time.
