• ProductID
• OrderDate

The Date table is a dimension table that contains the following columns:

You need to define a relationship from Products to OrderHistory and from OrderHistory to Date.

Nothing in the question indicates that there is at most one order per day. If there is more than one order per day then "one" date in the Date table would map to "many" dates in the OrderHistory table

The given answer is incorrect. It should be one-to-many, and then many-to-one. Without additional information provided, it would be rational to assume that the fact table has many dates which would relate to a single date in the date dimension table.

ye, but second option tells on-to-one, and the same like first option is relationing dim table with fact table, so must be one-to-many too. Am I wrong?

Given answer is correct. Dimension table is always the "one side", and fact table is always the "many side"
