Database integrity refers to the requirement that information be protected from
improper modification. Modification of data includes creation, insertion, updating,
changing the status of data, and deletion. Integrity is lost if unauthorized changes
are made to the data by either intentional or accidental acts. If the loss of system or
data integrity is not corrected, continued use of the contaminated system or
corrupted data could result in inaccuracy, fraud, or erroneous decisions.
