In online processing, the computer's files are updated as each transaction is processed. The processing does not need to be instantaneous. Examples of online processing can be found in supermarkets, where it is used to update stock quantities when goods pass though a computerized checkout; cash machines (ATMs); and ordering over the internet, for example an order for a book or a flight.
