Data Architect Interview Question:

Please explain semi Additive Measures?

Submitted by: Muhammad

Semi-additive measures are those where only a subset of aggregation function can be applied. Let's say account balance. A sum() function on balance does not give a useful result but max() or min() balance might be useful. Consider price rate or currency rate. Sum is meaningless on rate; however, average function might be useful.
