Data Model: Using Reference tables to merge in Categorizations for Dimension usage

Anonymous 

I looked at the model and I could recomment couple of approaches.

1. Bring Product segment to facts and join the segment dimension directly to facts intead on top of tax. The tax should join to facts as well. With this tax and segment both filter facts.

But for a single row in fact, if a segment tagged to core is different than a segment tagged to platform, we can't go for this appraoch.

2. Create bridge or linker table between tax and facts. This should have all the combination for segment, tax(core,product, platform etc) and facts. All 7 tax and segment dimension connects to bridge and the bridge connects to facts.

In any case, you can't join the dimension to seperate tax unless you merge them togeather. 

Let us know.
