Question

Quizplus · Accepted Answer

Factless fact tables are used when we are tracking events (option A) or taking inventory of the set of possible occurrences (option C) or when we have no measures or facts in the fact table. Therefore, option D, which includes both options A and C, is the best choice. Option B, tracking sales, would typically involve measures and facts, so it is not applicable for factless fact tables.
