Database users sometimes tend to create person objects together with
every new submission, resulting in duplicate person objects. This
damages the coherent integrity of the database since a 'real world'
relation fails to be reflected to the representation in the database.
Example
The following two objects are duplicate. Notice that the nic-hdl's of the
two objects are different.
