In recovery techniques, "atomic transactions" requires that all of a transaction be performed or none, so the recovery manager has to ensure that all the effects of committed transactions reach the database and that the effects of any uncommitted transactions be undone as part of recovery.

What are recovery techniques?

Generally, Atomic transactions are a fundamental concept in database systems and are used to ensure the consistency and integrity of the database.

They allow multiple operations to be grouped together and treated as a single unit of work, either all committing or all being undone.

This is especially important in the event of a system failure or crash, as it allows the recovery manager to restore the database to a consistent state without losing any data.
