About This Architecture

AirTickit System DFD Level 0 models a complete airline ticketing platform with six core processes: Authentication, Flight Management, Reservation, Payment Processing, Report Generation, and Admin Management. Data flows from external entities (Airlines, Payment Gateway, Email Service, SMS Service, Government Database) through sequential processes that interact with five dedicated data stores (User DB, Flight DB, Booking DB, Payment DB, Ticket DB). This architecture demonstrates separation of concerns and clear data ownership, essential for building scalable, maintainable booking systems. Fork this diagram on Diagrams.so to customize processes, add new data stores, or adapt it for your airline or travel platform requirements.
