Database

Using a relational database, such as MySQL, is recommended for storing data. The database tables should include at least tables for books, users, and loans. Here is a simple basic database structure:

• The "Books" table to store information about books.
• The "Users" table to store user information.
• The "Loans" table to track book loans, with information about the loan date and due date.
