Read and Relax Educate Hub is a cozy library environment set up by Alam Jaya

communities in Puncak Alam for the public to come and used its facilities. Library

management systems $($LMS$)$ help libraries automate the process of keeping track of their

books, magazines, CDs$,$ DVDs$,$ and other items. To enable proper management in

handling the borrowing and returning of books, a Library management system is

suggested to be developed based on the following system requirements.

Any library member should be able to search books by their title, author, and

subject category as well as by the publication date.

Each book will have a unique identification number and other details including a

rack number which will help to physically locate the book.

There could be more than one copy of a book, and library members should be able

to check out and reserve any copy. We will call each copy of a book, a book item.

The system should be able to retrieve information like who took a particular book

or what are books checked out by a specific library member.

There should be a maximum limit $(5)$ on how many books a member can check

out.

There should be a maximum limit $(10)$ on how many days a member can keep a

book.

The system should be able to collect fines for books returned after the due date.

Members should be able to reserve books that are not currently available.

The system should be able to send notifications whenever the reserved books

become available, as well as when the book is not returned within the due date.

Each book and member card will have a unique barcode. The system will be able

to read barcodes from books and members' library cards.

Based on the given scenario, with an aid of a diagram, construct the following UML

diagrams to present the design of Library Management System:
