Your ERD should clearly represent the relationships between these entities according to the provided business rules. Business Rules: In this system, users are able to rent multiple books. Once they check out one or multiple books, a unique rent record will be assigned to users to track their transactions with the library.

Book: Denotes books available in the library, each linked to a specific author. Author: Refers to the writers of the books available in the library. Rent: Records the details of the transaction when a library member rents a book. TASK REQUIREMENTS 1. Include all four entities (Member, Book, Author, Rent) in your ERD. 2.
