FUNCTIONAL SUBSET

derived from the model

SELECTIONfunctional division

The subset is the minimum list of necessary tables

ANONYMISATION

ListeRS.txt

To define the data anonymisation rules

The values of the attribute “RAISON SOCIAL” are read in the file "D:\Dgi\Database\ListeRS.txt"

VALUE DIFFERENCES

Some value difference between attributes were ignored ex: MODIFICATIONDATE
