Use case transactions are atomic set of activities which are either performed or not performed at all. For instance below figure ‘Atomic’ shows the meaning of atomic in context of use case transaction. The first transaction cycle does not show a complete atomic activity; rather the transaction is in between and is not in persistent state. If you see the second transaction cycle it’s atomic because after the user sends the email it’s in persistent state and is sitting on the mail server.
Figure: - Atomic
