Integrated Data Processing
It is a truism to state that every business transaction, however small, has repercussions throughout the data-processing system. It has long been the ambition of computer technologists to provide a fully integrated system on a computer, sometimes referred to as the ‘one-shot approach’, whereby each transaction will update every file affected by it, resulting in an immediate amendment of the final accounts. The imagination is fired by the prospect of the Managing Director being able to call up at any moment the up-to-date position of his company, for example the Profit and Loss account, on a video display unit in his office. This prospect is not so far away as many people think; already one large manufacturer of computers is rapidly approaching this objective. At the present moment managers can interrogate files relating to their responsibilities by remote terminals or video display units.
