+    Create a UML diagram for a **Library Management System** that includes classes such as **Book** (with attributes like `bookID`, `title`, `author`, `publisher`, `genre`, `availabilityStatus` and methods like `checkAvailability()`, `updateAvailability()`), **Member** (with attributes such as `memberID`, `name`, `email`, `phoneNumber`, `membershipDate` and methods like `borrowBook()`, `returnBook()`, `reserveBook()`), **Staff** (with attributes such as `staffID`, `name`, `role`, `email`, `phoneNumber` and methods like `addBook()`, `removeBook()`, `updateBookInfo()`), **Transaction** (with attributes like `transactionID`, `transactionDate`, `dueDate`, `fineAmount` and methods like `calculateFine()`, `generateReceipt()`), and **Reservation** (with attributes like `reservationID`, `reservationDate`, `expirationDate` and methods like `cancelReservation()`, `checkReservationStatus()`).
+
+    Define the relationships where a **Member** can borrow many **Books**, a **Staff** can manage many **Books**, a **Transaction** is linked to one **Book** and one **Member**, and a **Reservation** is made by a **Member** for a **Book**. Ensure appropriate visibility markers for methods and attributes, and include necessary relationships such as associations, multiplicities, and inheritance. Optionally, consider adding sequence or activity diagrams for processes like book borrowing.
