summary:
– Atomic, each unit of work is an all-or-nothing operation
– Consistent, db modifications do not leave db in an illegal state
– Isolated, isolating tx from each other, clients do not see each other’s work (locking)
– Durable, committed changes are permanent, the db keeps data once committed (persitence) and recovers to the end of the last committed transaction after system failure (logs, archives)
