La logique informatique
(selon les travaux de J.D WARNIER)
L.D.R The organization of all the outputs requested
Let us finish our example in such a way that it is decided not to subdivide Level 2 of the "Everyday management", and therefore to define the outputs requested at this level.
​
Here is the corresponding diagram:

It should be stressed that the subdivision criteria used to organize the outputs requested by users are arbitrary, the aim being to find a method of classifying the subsets which makes it possible to reduce A major problem to a series of restricted problems (*).
​
Note: It is understood that we call "Outputs Requested", any collection of data output from the computer system whatever its medium (Paper, screen, telecom etc.)
​
(*) What will be the main thread of all the studies of J.D WARNIER.
​
We have now finished the study of our first phase LDR ie to define and to organize the list of requested outputs of the computer system studied. I now propose to proceed with the study of the organization of the data relating to a requested output
