This application is a library

This application is a library application and consists of two parts: a librarian section and a regular user section.

The librarian section is responsible for:

1- Adding books, classifying them, determining the number of available copies of each book, and displaying an image of the book.

2- Responding to messages from users.

3- Removing books when they are unavailable.

4- Controlling the quantity of each book available.

The regular user can access the application and do the following:

1- Searching for books by name and classification.

2- Borrowing books and agreeing to return them after the specified loan period, or extending the loan period.

3- Viewing the history of previous borrowings.

4- Sending messages to the librarian section and viewing previous questions and answers.

5- If borrowed books are not returned on time, the system will impose a late fee and suspend the user's borrowing privileges until payment is received. Users can pay through the application using bank cards.
