RE: what are non-additive facts in detail?
 
 

Types of Facts

There are three types of facts:

  • Additive: Additive facts are facts that can be summed up through all of the dimensions in the fact table.
  • Semi-Additive: Semi-additive facts are facts that can be summed up for some of the dimensions in the fact table, but not the others.
  • Non-Additive: Non-additive facts are facts that cannot be summed up for any of the dimensions present in the fact table.

Cheers,
