Final answer:
Commit and rollback actions are crucial for ensuring the atomic property of a transaction in a database, meaning the transaction is treated as a single unit that either fully completes or does not occur at all, aligning with ACID principles for reliable processing.
Step-by-step explanation:
To ensure the atomic property of a transaction processing system, actions such as commit and rollback are essential. Commit refers to the action where a transaction is successfully completed and all the changes are permanently applied to the database. Conversely, rollback is the action taken when a transaction cannot be completed successfully, which causes all the changes made during the transaction to be undone, restoring the database to its previous state.
The primary behavior that these actions ensure is that a transaction is 'atomic', meaning it is treated as a single unit of work that either fully completes or has no effect at all (this prevents partial completion). This atomicity is central to the concept of ACID (Atomicity, Consistency, Isolation, Durability) properties for the reliable processing of database transactions.
