Name:suppression of incomplete, erroneous, or obsolete data
Incomplete or obsolete data is suppressed to prevent its
accidental use or intentional abuse. Examples include databases that remove
old records, record keeping processes that expunge data after statutory and
business requirements no longer necessitate its availability, and the destruction
of old criminal records by government when appropriate.
Complexity: Tracking obsolecense is rarely done well, however, if tracking
is properly done, suppression is not complex.
