Isolation ensures that concurrent transactions occur as if they were performed sequentially, meaning that each transaction is independent and isolated from others to maintain data integrity. Atomicity ensures that either all the operations in a transaction are completed or none are completed, consistency ensures that the database remains in a valid state before and after the transaction, and durability ensures that once a transaction is committed, its effects are permanent and can survive system failures.
