e. Since the Music Object extends the CD object it is also considered a CD since it is in CD format like the Books on CD and therefore is both objects.

Entity relationship diagram is also known as Entity relationship model. This model is used to design relational database by various sectors such as education, engineering, business, etc.
<u>ERD is designed using conceptual data model, logical data model, and physical data model</u>.
The visual practice or model that gives more insight into the logical relations among the entity is the logical data model.
