Designed with EdrawMax, this UML Class Diagram template models a library management system. It defines classes like *Book* (attributes: id, title, authors, isbn, availabilityStatus), *User* (attributes: id, email, phoneNumber; methods: borrowBook(), returnBook()), and *BorrowingHistory* (attributes: id, book, issueDate, dueDate). Subclasses *Librarian* (methods: manageBook(), monitorOverdue()) and *Author* (method: PublishBook()) inherit from *User*. Relationships visualize interactions (e.g., User borrows Book, linked to BorrowingHistory). Ideal for architects to design and document library system logic.
