Answer
It logically undoes previous steps if a transaction fails.
Compensating transactions are crucial in Sagas to handle failures by reversing actions. Unlike a database rollback, they perform business logic to undo operations. For example, if an order placement fails after payment, the compensating transaction would issue a refund instead of simply rolling back a database entry.
