An instructor has an ID, a name, and a phone number. An instructor teaches a course.

A course has a code, course name, credits, and an instructor. Each course uses a textbook.

A textbook has ISBN, name, publisher, editor, and authors.

Your ER diagram should have entities, attributes, composite attribute, multivalued attribute, key attributes, binary relationships, and a total participation. Explain your rationale behind each design choice.
