In this UML component diagram for a Library Management System, square-shaped components represent the system components, with each component's name listed inside. Fork-like shapes denote the required interfaces, while the lollipop-like shapes represent provided interfaces within the system. Dotted arrowed lines illustrate dependencies of one component on another. The diagram shows the process of issuing a book to a member. Here the system first validates the member's membership. If a member, a transaction for book rental is initiated, and the book status within the system is updated accordingly.
