Question

Quizplus · Accepted Answer

The entity CUSTOMER can have the attribute ADDRESS, indicating that each customer has an associated address. A product would not have an attribute of purchase, as it does not purchase anything, nor would it have an attribute of customer, as it does not relate to a specific customer. The option A presents the opposite of what is expected (a customer does not have a product attribute), while the option C and D assume a reverse relationship between the entities and attributes, which is not typical in the entity-relationship model.
