How do you draw a dfd for flight booking system?

Answer 1

To draw a Data Flow Diagram (DFD) for a flight booking system, start by identifying the main processes, such as "Search Flights," "Book Flight," and "Process Payment." Then, outline the external entities like "Customer," "Airlines," and "Payment Gateway." Use arrows to represent data flows between these entities and processes, indicating the information exchanged, such as flight details and payment confirmations. Finally, ensure each component is clearly labeled for easy understanding of how data moves through the system.
