Using this illustration of booking seats on a flight, below sequence of events would occur:
- Customer/travel agent contacts the airline
- Customer/travel agents types in day/time of flight and number of travellers
- Customer/travel agent types in departure airport and the destination airport
- Airline database is searched and availability of seats checked
- Seats are available on the required day/time then a booking is made
- Database/file is updated immediately to indicate that these seats are no longer available and prevents double booking from occurring
- If no seats are available a message is sent back to customer/travel agent
- This uses real time (transaction) processing as files are updated in real time; interrogation of files will have access to totally updated information
