基于数据仓库的决策分析系统技术研究

Research on the Key Technologies of Based on Data Warehouse Decision Support System (DSS)

在构建决策分析系统过程中,采用计算列方法和视图法进行数据变换与清洗,选择多维OLAP、关系OLAP、混合OLAP存储模式对提升决策分析系统性能有很大的作用。

Using computation row and the view method to carry on the data conversion and the clean in constructing DSS,selecting multi-dimensional OLAP,related OLAP,hybrid OLAP storage pattern to promote the performance of DSS.
