The following UML communication diagram illustrates the issuance process of a book to a member within a library management system. Initially, the librarian checks the book's availability within the inventory system of the library. If the book is available, the librarian proceeds to validate the member's membership status while also verifying if any dues remain unpaid by the member. Upon successful validation, the librarian generates a bill for the renting of the book and proceeds to issue the book to the member.
