Confusion remains to this day between the terms « Data Mining » (DM), translated into French as « Fouille de Données » (FD), and Knowledge Discovery in Databases (KDD),
translated into French as « Extraction de Connaissance à partir de Données» (ECD). For
many researchers and practitioners, the term DM is used as a synonym for ECD in addition to being used to describe one of the steps in the ECD process. It is for this reason that this
article has set itself the main objective of giving the main theoretical meaning
s between the two concepts (FD and KDD) and trying to explain the difference that would exist in terms of process, storage and data access.
