Data Modelling

Previously I had a nice star schema type of relationships as per the above image.

Now I have to add a new table Master_Table as per below to generate the below table.

Which means I am not using middle Dimension Table in my Matrix. Will this give me accurate results?

1-to-many relationships

• Master_Table[M_Code] → Dimension[Star_Code]

• Dimension[Star_Code] → T1/T2/T3

Single-direction filtering

• From Master → Dimension → Facts

• No bi-directional shortcuts

Grain is respected

• Each M_Code maps deterministically to Star_Code(s)

• No ambiguous many-to-many paths

If these are met, the Dimension table still acts as the logical bridge.
