Yet this attitude ignores the fact that more time can be wasted in a system by bad data capture techniques than can ever be saved by even the most elegant programming. Similar considerations can also be applied to input and output. Fu

Traditionally each analyst has been responsible for the collection and storage of the data for ‘his’ applications. This approach is inherently wasteful in that it leads to duplication and inconsistency when data is required for different purposes. Mo
