re: Slowly Changing Dimensions Are Not Always as Easy as 1, 2, 3
I have a situation where a dimension has two hierarchies, but they don't intersect. I.e. dimension can have member A from hierarchy H1, member B from H2 etc. If I model it as snow flake then the leaf level table will have two FK (one for each hierarchy, value = NULL for members that belong to the second hierarchy). Is this a common practice?
