Answer 1

false

Commit followed by rollback does not have any effect on the transactions in database.

Answer 2

Answer: True

Explanation:

Once a transaction has been committed, we cannot undo its effect by aborting it or by rollback.

Commit is the updation of a record in a database. In database transaction, a commit refers to the saving of data permanently after a set of tentative changes.

In database technology, a rollback is an operation which returns the data to some previous states.
