This state diagram represents a library management system. Starting at 'Idle', users can log in as an admin or user, accessing different menus and functionalities such as viewing, adding, removing books, borrowing, returning, and handling book operations. Actions like borrowing, returning, adding, or removing books lead back to the 'Idle' state, while successful book addition loops back to the 'AdminMenu', culminating in an end symbol, '[O]', indicating completion.

About state diagrams
State diagrams, a subset of UML's behavioral diagrams, visualize object lifecycles and transitions, pivotal in computer science. These diagrams portray system states, transitions, and event triggers, aiding software, circuits, and protocol designs. In modeling reactive systems, they clarify responses to internal or external events, bridging understanding across technical and non-technical stakeholders. State diagrams are indispensable tools, enabling comprehension and illustration of intricate system behaviors.
