About the use case diagram example

The use case diagram for a flight reservation system outlines interactions among primary actors—Passenger, Agent, and Administrator—and the system’s functionalities. Passengers interact with the system to search for flights, book tickets, manage reservations, and check flight statuses. Key use cases for passengers include searching for flights by date and destination, selecting flights, booking tickets, and managing personal reservations. Agents engage with the system by assisting passengers with booking, managing ticket availability, and handling special requests. Key use cases for agents involve assisting passengers with booking flights, checking ticket availability, making reservations on behalf of customers, and managing booking modifications.

Administrators manage the system by overseeing flight schedules, managing user accounts, and addressing technical issues. Key use cases for administrators include managing flight schedules, handling user accounts, and resolving technical support requests. The diagram uses ellipses to represent these use cases, with lines connecting the actors to their respective actions, illustrating the workflow and coordination essential for efficient flight reservation management. This visual representation facilitates understanding of the system’s design, identifies areas for enhancement, and ensures a seamless booking experience for all stakeholders involved in flight reservations.
