Online banking transactions are being posted to the database
when processing suddenly comes to a halt. The integrity of
the transaction processing is best ensured by:
A. database integrity checks.
B. validation checks.
C. input controls.
D. database commits and rollbacks.
Answer / guest
Answer: D
Database commits ensure the data are saved to disk while the
transaction processing is underway or complete. Rollback
ensures that the processing already completed is reversed
back and the data already processed are not saved to the
disk in the event of the failure of the completion of the
transaction processing. All other options do not ensure
integrity while processing is underway.
