system. The system needs to track books, authors, members, and book loans.
The requirements are as follows:
•
Each book has a unique ISBN, title, publication year, and genre. A book
can have multiple authors.
•
Each author has a unique author ID, name, and nationality.
•
Each member has a unique member ID, name, address, and
membership date.
•
Each loan records the loan of a book to a member and includes the loan

•
Authors can write multiple books, and a book can have multiple authors.
•
Members can borrow multiple books, but a book can only be borrowed
by one member at a time.
Given the scenario above, design the relational schema for the library
management system. Identify the tables, their attributes, primary keys, and
foreign keys. Explain the constraints you would apply to ensure data integrity.
