The entity relationship model below shows the relationship between Product and Order. Which of the following business rules is correct and is reflected in the diagram?
I'm a bit confused by this question. The diagram doesn't seem to specify a maximum number of products per order, so I'm not sure if A or B is the right answer.
Okay, let's see here. The diagram shows a one-to-many relationship between Product and Order, so that gives me a clue. I think the answer is probably B or D.
The key here is to focus on the wording of the question - it's asking about the date the product is no longer sold or developed. I'd say that's most likely the End of Maintenance (Transition) option.
I disagree, I think the correct business rule is B) The maximum number of products on one order is unlimited, because there is no limit shown in the diagram.
B seems more logical to me. The maximum number of products on one order should be unlimited, as there's no cap on the number of items a customer can order.
I think the correct answer is D. The minimum number of products on each order is zero, which is reflected in the one-to-many relationship between Order and Product.
