Question 80

You have sales data in a star schema that contains four tables named Sales, Customer, Date, and Product. The Sales table contains purchase and ship dates.

On the Date table, use a reference query in Power Query and create active relationships between Sales and both Date tables in the modeling view.

Create an active relationship between Sales and Date for the purchase date and an inactive relationship for the ship date.
