Answer / s
Transactions are programs that run under the transaction
managers like CICS, IMS/TM. Transactions require excellent
response times.
Commit makes the database changes permanent that was made
during a unit of recovery ie. from one consistency point to
another.
Rollbacks reverses the changes made to the database during
a unit of recovery.
