Sequence diagram for online movie ticket booking

About this sequence diagram for online movie ticket booking

This UML sequence diagram shows the online movie ticket booking system. It is an interaction among four components: customer, booking system, payment gateway, and cinema system. All these parts help create a good flow from movie selection to booking confirmation.

The first activity in this process is where the customer searches for available movies. The booking system receives the request. It queries the cinema system for available movies and their showtimes. The booking system shows the customer all movie options to help them choose. This transaction ensures the customer has the correct info on all current screenings.

Next, the customer books the seats for the selected movie. The booking system verifies the selected seats with the cinema system for availability. The booking is then confirmed. Once successful, the customer enters their payment details to complete the booking.

The booking system then uses the payment gateway to handle the payment securely. It checks the customer's payment details. Then, it states if the transaction was successful. If so, a confirmation will be sent back to the booking system.

On payment confirmation, the booking system updates the cinema system. It finalizes the booking and marks the reserved seats as sold. It then sends the booking confirmation and ticket details to the customer, completing the process.

The UML sequence diagram for the online movie ticket booking shows the proper flow of info between the customer and the back-end systems. This will ensure a smooth, accurate, and secure booking experience. It also shows how an integrated multi-system should make ticketing efficient.
