Data which is already stored in the computer may be accessed from either central memory (226-2) or from one of the mass storage devices (226-3) and used as input data. This is part of the data collection 3★ which goes from extraction (220-1) to the transcription on an electronic medium, through validity checks (221-7) and consistency checks (221-18 that can be made ​​during data entry when working on line.

In a third phase, occasionally referred to as output phase, the processed results 6 or output 6 may be printed out on the line printer (227-6) or saved as a file on a mass storage device (226-3) for further processing.
