2. 2 FUNCTIONAL SUBSET derived from the model …and the usage graph SELECTION functional division The subset is the minimum list of necessary tables

3. 3 VOLUMETRIC SUBSET rules definition for all the functional subset attributes SELECTION volumetric division

4. 4 RULE TYPES 1. Simple criteria x = valeur 2. borders x <= 0007 0008 <= x <= 0011 0012 <= x 3. Addition or suppression of known records SELECTION volumetric division

10. 10 ANONYMISATION

11. 11 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" RAISON SOCIALE 00001 RAISON SOCIALE 00002 RAISON SOCIALE 00003 RAISON SOCIALE 00004 RAISON SOCIALE 00005 RAISON SOCIALE 00006 RAISON SOCIALE 00007 RAISON SOCIALE 00008 RAISON SOCIALE 00009 … ANONYMISATION

12. 12 ANONYMISATION

13. 13 For each record “ SUPPORT JURIDIQUE” create randomly 1 to 3 record TIERS DATA GENERATION Generation rules

17. 17 To define comparison criteria’s Looking for differences Some attributs might be different ANALYSIS / VALIDATION

18. 18 <SUPPORTJURIDIQUE IDSJU = "53385" <TIERS IDTIERS = "85524" <DEFAILLANCE IDDEFAILLANCE="80307"/> > <TIERS IDTIERS = "85523" > <SUPPORTJURIDIQUE IDSJU = "53385" <TIERS IDTIERS = "85524" <DEFAILLANCE IDDEFAILLANCE="80307"/> > record TIERS 85523 was cancelled DB 1 extraction DB 2 extraction ANALYSIS / VALIDATION

19. 19 VALUE DIFFERENCES Some value difference between attributes were ignored ex: MODIFICATIONDATE The path to the record is detailed The critical differences are detected ANALYSIS / VALIDATION
