The selection of entities considered for MDM depends somewhat on the nature of an organization. A common case is the commercial business, for which MDM applies to such entities as customer, product, employee, and vendor. MDM processes identify the sources from which descriptions of these entities can be collected. In the course of transformation and normalization, the descriptions are conformed to standard formats and data domains, so what duplicate instances of any entity can be removed. The result of these processes would generally be an organizational MDM repository, from which, all requests for a certain entity instance produce the same description, irrespective of the originating sources and the requesting destinations.
