Library Management

Level: Intermediate

Concepts: State Business Rules

Implement a library management system that handles book checkouts, returns, and reservations. The system should manage book inventory, track due dates, and handle various library policies.

Requirements

  1. Manage book inventory
    • Add and remove books
    • Track book status (available, checked out, reserved)
    • Handle multiple copies of the same book
    • Manage book categories and locations
  2. Handle checkouts and returns
    • Process book checkouts
    • Track due dates
    • Handle late returns
    • Calculate fines
  3. Manage reservations
    • Place and cancel reservations
    • Notify when reserved books are available
    • Handle reservation queues
    • Expire old reservations

Hint

Start by implementing the basic book management functionality, then add checkout and reservation features. Consider using a state machine to track book status. Think about:

  • Data consistency and validation
  • Concurrent access handling
  • Business rule enforcement
  • Error handling and edge cases

Bonus

  • Implement a patron management system
  • Add support for different types of library materials
  • Create a recommendation system
  • Implement a search and filtering system
  • Add support for e-books and digital content
