摘要
基于校园一卡通系统数据仓库中的数据集,通过分析确定应用系统中各主题,并对其进行维度设计,依次创建维表和事实表,最后设计出用于OLAP分析的多维数据系统架构,借助OLAP技术,为进一步数据挖掘奠定基础。
Based on the data sets of the campus IC card data warehouse,the present work first determine each subject of the application system by analysis,design it＇s dimension,and build the dimension tables and fact tables.At last,the multi-dimensional data system structure for OLAP analysis is given.This will be the basis of data mining by using the OLAP technology.
