Whenever Microsoft SQL Server is restarted, the tempdb is recreated. Any data that was committed to the tempdb is lost and replaced by a fresh copy from the model database, therefore violating the durability property which states that the effect of a transactoin must be persisted within the database irrespective of the state of the system.

ur explanations are short and clear

but still am stacked with atomicity and consistence. im understanding as if they are speaking the same concepts.
they all explain that the transaction must complete otherwise rollback all changes?

plz can u clarify for me to kill all my dought

Ex:
BEGIN TRANS

–PERFORM your actions Updates/deletes/insert/truncate

IF @@TRANCOUNT>0
COMMIT TRANS
ELSE
ROLLBACK TRANS

To be more specific, how is atomicity achieved in the database?

If atomicity is fullfilled how could consistecy (from your definition) fail?
