3. Relationships and Interactions

Association

  • BookInfo and Author: A book has an author.
  • Book and BookInfo: A book has information associated with it.
  • Book and Transaction: A book can be involved in transactions.
  • Transaction and Borrower: A transaction involves a borrower.
  • Transaction and Borrow: A transaction can involve borrowing a book.

Aggregation

  • Book and BookInfo: A book aggregates book information.
  • Book and Author: A book aggregates author information.

Composition

  • Transaction and Borrow: A transaction composes borrowing details.
  • Transaction and Reservation: A transaction composes reservation details.

Dependency

  • Transaction depends on Book and Borrower.

Generalization

  • Borrow and Reservation: Both are types of transactions.

4. Use Cases

Use Case 1: Borrowing a Book

  1. A borrower selects a book to borrow.
  2. The system creates a Transaction for the borrowing process.
  3. The Borrow details are recorded, including the return date.
  4. The borrower receives the book, and the transaction is completed.

Use Case 2: Reserving a Book

  1. A borrower reserves a book that is currently unavailable.
  2. The system creates a Transaction for the reservation process.
  3. The Reservation details are recorded, including the available date.
  4. The borrower is notified when the book becomes available.

Use Case 3: Returning a Book

  1. A borrower returns a book.
  2. The system updates the Borrow details to indicate that the book has been returned.
  3. The transaction is marked as complete.

5. Conclusion

The Library Management System, as illustrated by the class diagram, provides a comprehensive solution for managing library operations. By understanding the key concepts, relationships, and use cases, one can effectively design and implement a robust library management system. This system ensures efficient tracking of books, authors, transactions, borrowers, and reservations, providing a seamless experience for both library staff and users.
