Atomicity is an all-or-none proposition.
Consistency guarantees that a transaction never leaves your database in a half-finished state.
Isolation keeps transactions separated from each other until they’re finished.
Durability guarantees
that the database will keep track of pending changes in such a way that
the server can recover from an abnormal termination.
OR
Durability ensures that any transaction committed to the database
will not be lost. Durability is ensured through the use of database
backups and transaction logs that facilitate the restoration of
committed transactions in spite of any subsequent software or hardware
failures.
