Assignment: Entity$-$Relationship $($ER$)$ Modeling for a Library Database

Objective: In this assignment, you will apply ER modeling principles to design a database schema for a library system. You will identify entities, attributes, relationships, and constraints to create an ER diagram.

Scenario: Imagine you are tasked with designing a database for a library. The library has books, patrons $($library members$),$ authors, and multiple copies of each book. Each patron can borrow multiple books, and each book can be borrowed by multiple patrons. Additionally, books have authors, and authors can write multiple books.
