摘要
介绍了OLAP的概念 ,OLAP的分类 ,ROLAP和MOLAP的比较分析 ,OLAP与数据仓库的关系 ,OLAP工具的评估 ,流行的OLAP工具 ,为提高OLAP的性能可以采用星型模式组织数据、采用索引技术、大的数据表分片为许多小表、维的逆规范化、构建概要表。
This paper introduces the concept of OLAP, classes of OLAP, comparison and analysis of ROLAP and MOLAP, relations between OLAP and data warehouse, evaluation of OLAP kits, prevalent OLAP Kits. To raise the performance of OLAP, one may employ star-pattern mode to organize data, employ index technic, divide large datasheet to many small datasheet, normalize dimension inversely, construct summary sheet, employ parellel inquiry technic.
