My February post @All Analytics.
"A fact is represented in the database not because it is categorically
true, or categorically false, but only because somebody has asserted
it, or has removed that assertion. We rely on people (and only on
people!) for whatever a database system treats as true or false. When we
authorize someone (or some application) to update the database, we
accept their veracity, judgment, personal integrity, intelligence,
comprehension, etc. insofar as the database is to have any utility.
Nothing more can (or should) be said about truth and falsity." -- David
