A- ATOMIC : Atomic transactions are either completely get success or completely failed. 

C- CONSISTENCY : Data is inserted obeying the constrains applied on the database tables strictly.

I- ISOLATION : If more than one transaction need to happen concurrently, they are executed without affecting other transaction execution. It can be in an order but order can not be predicted. 

D- DURABILITY : Once transaction is executed completely data is saved even after crash or power failure.


A database must follow ACID property.
