rollback - Reverting data in a database to an earlier state, usually in response to an error or aborted operation. In a transaction based database system, transactions are considered atomic. If an error occurs while performing a transaction, the database is automatically rolled back to the state at the previous commit. Rollback may also be performed by an explicit rollback transaction.
