Suggested Answer: E 🗳️
Many to Many Dimension Relationships.
In most dimensions, each fact joins to one and only one dimension member, and a single dimension member can be associated with multiple facts. In relational database terminology, this is referred to as a one-to-many relationship. However, it is frequently useful to join a single fact to multiple dimension members. For example, a bank customer might have multiple accounts (checking, saving, credit card, and investment accounts), and an account can also have joint or multiple owners. The Customer dimension constructed from such relationships would then have multiple members that relate to a single account transaction.

I believe question is asking to list Shipped country over product Analysis which is Many to Many

Each shipment ID is a natural unique key, the shipment Id's don't repeat. So each shipment goes to only one country. The country keys in the shipment table do repeat, so that's a Many on one side of the relationship. On the countries table, each country key is unique, so that's a One on the other side of the relationship. This is a Many to One, ie. a regular relationship. Answer B.

I agree with you for relationship between country and shipment but my doubt was to have new dimension to include shipment, country and product. For this I still stick to Many-Many

Shipment Fact is a factless fact and its related to a dimension(country). we are going to analyse by product.

I agree. The analysis must be done per product, so the answer is many-to-many in my opinion.

It looks like the answer is regular dimension in first sight but after checking carefully here is my argument: We must consider the relation between Country and product. So 1 product is sold in many countries from different shipments and also in 1 country are sold many products from different shipments. So I think the answer many-to-many is correct.

I've never known any single shipment to be shipped to more than one country.

That's maybe true but there are multiple orders being shipped to multiple countries. Which makes it an many to many reference.
