Atomicity − This property states that a transaction must be treated as an atomic unit, that is, either all of its operations are executed or none. Consistency −If the database was in a consistent state before the execution of a transaction, it must remain consistent after the execution of the transaction as well. Isolation −the property of isolation states that all the transactions will be carried out and executed as if it is the only transaction in the system. No transaction will affect the existence of any other transaction. Durability − The database should be durable enough to hold all its latest updates even if the system fails or restarts.
