Ah, the joys of database relations. It's like playing a game of 'Catch the Dangling Foreign Key' - you never know what's going to get deleted next!

Wait, so if I delete an order, the customer and receipt just vanish into thin air? That's like deleting your entire Amazon order history - poof, gone! Talk about a magic trick.

Hmm, I'm going with C. Deleting a customer should delete the order, but deleting an order shouldn't delete the customer. Gotta be careful with those referential integrity rules, you know?

Definitely, deleting a customer should cascade to the order, but not the other way around.

D? Really? That can't be right. If you delete a customer, it should delete the order as well, not just the customer. These questions can be so tricky sometimes, ugh.

I see your point. It can be confusing sometimes to understand the relationships between entities.

But if you delete a customer, shouldn't it also delete the order associated with that customer?

I think D is correct. Deleting a customer should only delete the customer information, not the order.

Okay, let's see... Option B seems to be the correct answer here. You can't delete an order because it's referenced in the OrderProduct table, but you can delete an OrderReceipt and it'll take the order with it. Simple enough!

That makes sense, you can't delete an Order because it's referenced in the OrderProduct table.

I see your point, Skye. But I think the correct answer is C. Deleting information in Customer should delete information in both Customer and Order. It just seems more logical to me.

I disagree, I believe the correct answer is B. It makes sense that you cannot delete information in OrderProduct table from Entity Order, but deleting information in OrderReceipt will delete information in both OrderReceipt and Order.
