A state machine diagram illustrates the states within the system, such as the management, customer, and staff systems. User interface dialogue boxes are presented, along with a conclusion summarizing the system's design and functionalities. The project concludes with a comprehensive bibliography, referencing relevant sources on system analysis and design.
