In order to manage import and export to and from a quite big email data base, I need a program based on Access or another free Data Base tool.
Program must do following :
Import CSV list emails and describing this import : Origin, Date import, fields to import,..
Insert emails imported in the main data base when new emails, managing relation to the import data base and when not new email only writing relation to this import data base
Possibility to compute select to choose export email data base
Export these data base in CSV form
Very precise description in french is available, could be translate if interested
