Question

Quizplus · Accepted Answer

An ER diagram depicts the logical design of a database from a top-down perspective, illustrating the relationships between entities and their attributes. It is a conceptual model that is used to design the database schema, which is the blueprint for the physical structure of the database. The ER diagram does not represent the actual physical design of the database, which involves the organization and storage of data on a physical medium like a hard drive or solid-state drive. Therefore, choices B, C, and D are incorrect.
