A transaction is a set of operations who share a common objective and are interdependent. This set also accomplish the ACID properties. The acronym ACID responds to the terms explained below:

Atomicity: the set of actions has an atomic character, it means that the operations are carried out in their entirety or none is done.
Consistency: A transaction mantains the consistency of the data, transforming them from a coherent initial state to an equally coherent final state.
Isolation: Each transaction behave as if it were the only one running on the system, although other transactions are running at the same time.
Durability: If a transaction is successful, the system guarantees that your updates are maintained, even if the equipment fails immediately after confirmation.
Axional Studio XSQL-Script allows at most one transaction initiated at any time.
