Atomicity

Atomicity is the first stage of the ACID model

Atomicity states that database modifications must follow an "all or nothing" rule. Each transaction is said to be "atomic." If one part of the transaction fails, the entire transaction fails.

Atomicity is the first stage of the ACID model (Atomicity, Consistency, Isolation, Durability), which is a set of guidelines for ensuring the accuracy of database transactions. 

It is critical that the database management system maintains the atomic nature of transactions in spite of operating system or hardware failure.
