Data flow diagram for airline reservation system

About this data flow diagram for airline reservation

The data flow diagram (DFD) shows how data moves between elements that handle airline reservation operations. The process begins when the passenger searches for available flights using the interface. Passengers can enter search criteria.

This helps the system show relevant flight options. The system gets all the details about the chosen flight as soon as the passenger selects it. This includes flight availability, pricing, and schedule information.

The airline reservation system gets flight information from the flight database. The flight database includes all flight information. It has booking details, schedules, and seat availability. The reservation system provides the passenger with all data before they can confirm their booking. The system updates the flight database with the new booking. It also keeps seat availability records accurate after confirmation.

A payment gateway operates within the system to process monetary transactions. When passengers complete their booking, the payment gateway handles the payment. It sends a confirmation message to confirm the transaction. The payment process concludes the booking and generates a confirmation for passengers.

The flight database plays a key role. It stores and retrieves data during the entire process. The database stores booking info. It updates flight schedules and keeps data accurate and up to date for all records. The data flow diagram shows how passenger data flows. First, it goes to the reservation system. Then, it moves through the payment gateway. Finally, it reaches the flight database. The DFD ensures the successful implementation of a flight reservation system.
