微软BI 之SSAS 系列 - 多维数据集维度用法之一 引用维度 Referenced Dimension

在 CUBE 设计过程中有一个非常重要的点就是定义维度与度量值组关系，维度的创建一般在前，而度量值组一般来源于一个事实表。当维度和度量值组在 CUBE 中定义完成之后，下一个最重要的动作就是定义两者之间的关系。在前面几篇文章中也已经看到了如何将度量值组和维度通过哪些维度属性进行关联的操作，但是那些关联通常都是 Regular 类型的，属于直接的普通的关联。

但是实际上除了 Regular 之外，还有 Fact, Referenced, Many to Many 和 Data Mining(数据挖掘类不在此讨论)。

今天在这篇文章中讲解 Referenced 和 Fact 两种关系的定义。

使用的测试代码如下 -
