Question 240
A transactional table has one row per purchased item and contains OrderID, ProductID and Quantity. What is the MOST appropriate Power BI design decision?
Explanation
Correct Answer
Transaction facts record measurable events at their explicit detail grain, supporting model per-item purchase events.
Incorrect Answers
Conformed dimensions support consistent filtering across multiple facts. It would address analyze separate business events with consistent product categories, not model per-item purchase events.
Star schemas keep numeric transactions at fact grain and descriptive filters at unique dimension grain. That targets report sales using shared descriptive dimensions, not model per-item purchase events.
Unique dimensions provide descriptive attributes that filter related facts. It is useful for filter facts through one-to-many product attributes, not for model per-item purchase events.
