The sequence diagram outlines interactions within a Travel Management System. The traveler requests travel booking, triggering the Travel Management System to check availability with the Database. Upon confirmation, the system confirms booking with the traveler and sends booking details to the Airline System. The Airline System confirms the booking, and the Travel Management System notifies the traveler. The traveler makes payment, and upon confirmation, the Travel Management System notifies the traveler. The traveler must confirm booking within 24 hours.

About sequence diagrams
Sequence or event diagrams help create an overview of how a system works. Sequence diagrams show how all the different parts interact with each other over time, carry out the required actions, and complete processes.
