Transaction Atomicity has four attributes:-ACID (atomicity,
consistency, isolation, and durability) is an acronym
device for learning and remembering the four primary
attributes ensured to any transaction by a transaction
manager (which is also called a transaction monitor). These
attributes are given below:
Atomicity. In a transaction involving two or more discrete
pieces of information, either all of the pieces are
committed or none are.

Consistency. A transaction either creates a new and valid
state of data, or, if any failure occurs, returns all data
to its state before the transaction was started.

Isolation. A transaction in process and not yet committed
must remain isolated from any other transaction.

Durability. Committed data is saved by the system such
that, even in the event of a failure and system restart,
the data is available in its correct state.

Answer / swapna

We must ensure that the entire transaction is either
committed or rolled back.
