Final answer:
The state of a database after a transaction has been rolled back is known as 'Aborted'. This ensures that the database reflects the state before the transaction began and remains consistent.
Step-by-step explanation:
The state after a transaction in a database system has been rolled back and the database has been restored to its state prior to the start of the transaction is known as Aborted. When a transaction is aborted, all the operations that were performed in the transaction are undone, ensuring that the database remains consistent and reflects the state before the transaction began. This happens typically in response to some error condition or manual intervention.
