The sequence diagram depicts interactions within a Railway Reservation System. A passenger requests a reservation, initiating a request to the Railway Reservation System. The Railway Reservation System checks availability by querying the Database. The Database returns availability information to the Railway Reservation System.

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.
