Quizplus · Accepted Answer

A composite relationship is used to represent a whole-part relationship where the part cannot exist without the whole. In the context of a sale, the sale items are parts of the sale and cannot exist without the sale. Therefore, a composite relationship would best describe the relationship between the sale and the sale items. An aggregate relationship would be used to represent a whole-part relationship where the part can exist without the whole, which is not the case in this scenario. Inherited and abstract relationships are not applicable in this context.
