Quizplus · Accepted Answer

Part number, type, and cost are examples of attributes, which describe specific characteristics or properties of an entity in an entity-relationship data model. Entities represent objects, concepts, or events in the real world, while relations describe the associations between entities. Objects are instances of classes in object-oriented programming, which is a different concept from the entity-relationship data model.
