software DB-Main to do a reversed engineering by analysing the databases and the
programs. The result is a conceptual model from which a logical model for any
type of database system can be derived down to the operative schemes (Hainaut &
Henrard, 2003; Hick & Hainaut, 2003; Henrard, Hick, & Thiran, 2003).
