PersonalDataStripper

Introduction:
With many countries introducing rules to safeguard the personal data stored in the database, it is diffucult
for the developer to replicate a user database in its office.
With this program you can have the same client database, but without the private data.


Each database table will be saved in a bunch of dataset files to avoid occuping excessively the memory during 
the export phase.

Each exported table has the following attributes:
set of key fields, and for each field optionally an operator and ids to eventually limit the output data.
This is a filter.

es: where id < xxx and id > yyyy


for each field in the table we can apply a rule:

1- Compose the value in a set of predefined values with the same initial (to maintain the same distribution as the original tabel)
 es:
 prename: M->mario,michele,massimo, and a counter. If there no an appropiathe choice, then program can 'invent' a value
 
2- Picture with random or predefined data (es: ssn)

3- A special rule ( es: codice fiscale italiano) with a checksum ,etc. For this maybe a plugin interface has to be declared

4- A casual date +- a delta from the original one ( birth date )

5- A composition (address: via,street, largo ,a set of names , and a number )

6- A code from another table ( es: city table ).


A special treatment apply to the random fields which are unique in its table or foreign keys of another table.
