Hi,
ich have on one side a wager. That is my first fact_wagers. It has attributes like:
One the other hand I have a fact for the winnings: fact_wins. This occurs later than the wager got created.
It has attributes like:
The relationship between them is 1:n , because one wager could have multiple winnings, because of his first and second product. One win in the first_product is related to one row in the winnings. A win in the second_product creates another row.
How would you join those facts?
Make a dim_wager_id as a degenerated dimension, because I would need that for filtering?
Cheers

Hi @Anonymous !
I would model this slightly different;
Dimesnion:
DimWager (Unique WagerID)
DimProduct (Unique ProductID)
Fact: (Bridging Table)
FactWagerProductWins (WagerID, ProductID, WinAmount) - Wager can have multiple ProductID, you don't need to create separate column for each ProductID
Relatiionships:
1 - Many between DimWager - FactWagerProductWins (based on WagerID)
1 - Many between DimProduct - FactWagerProductWins (based on ProductID)
This will remove the of separate FactWager (which has only WagerID & ProductID mappings)

That is interessting. In which cases you are able to design a fact_table as a dimension_table?
I mean a wager is in this context a business event, which a customer produces. I never thought about to design this a dimension. Is it allowed to insert a lot of entries to a dim_table?
