Scenario:
Library Management System is a software used to manages the catalog of a library. This helps to keep the records of whole transactions of the books available in the library. A normal user wants to borrow a book from a library. Initially the user searches the book in order to borrow the book. It is required to check the validity of the user. In order to fulfill the requirement the user has to go through an authentication system by logging in or signing up. If the user is eligible to borrow the book, then it is checked whether the book is available or not to the library. If the book isn't available then the user has to go through the booking process where need to wait until any copy of that book is returned. A call number with a slip is given to the user and the book will be delivered to the user for 15 days and can issue 3 books at a stretch. After receiving the book from the library, the user information is updated to the library database. When the book is unavailable then the user will be sent to the booking list. If any copy of that book is returned by anyone, the first booked person will be notified by sending a mail. If he doesn't borrow the book after 24 hour of sending the mail his request will be deleted. Whenever anyone wants to re-issue any book, the user need to return the book and extend the duration. Then the librarian will re-issue the book with a new time length if he has no fines due and a clearance. If a user or borrower cannot give the book in time then the user has to pay the fine and the fine increases day by day.
