Give example of Real time (transaction) processing

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
