Transaction Rollback

When you roll back a transaction, either automatically, or by explicit user request, you undo all of the operations in that transaction.

Rolling back the database means returning the database to an earlier state.

  Rollbacks can occur either due to an explicit user request, or automatically.
• Effect of Rollback
  Rollback returns both the main and temporary stores to their former state, and also releases locks.
