关系数据库中的外键关系,但也可能基于数据源视图中定义的逻辑关系。
<你能解释一下你的商业场景吗?
Can I link a dimension to the fact using non key attribute column in the dimension?
MG
解决方案
A regular dimension relationship between a cube dimension and a measure group exists when the key column for the dimension is joined directly to the fact table. This direct relationship is based on a primary key–foreign key relationship in the underlying relational database, but might also be based on a logical relationship that is defined in the data source view.
