What is the primary method to ensure the integrity of transaction processing in a database?

Ensuring the integrity of transaction processing in a database primarily relies on the mechanisms of database commits and rollbacks. This method is crucial as it allows for the management of transactions in a way that ensures that all parts of a transaction are completed successfully before making any changes permanent. When a transaction is committed, it signifies that all the operations within that transaction have been completed without errors, and the data reflects those changes accurately.

Conversely, if a transaction encounters an error or fails to meet specific criteria, a rollback can be initiated. This process reverts the database to its previous state before the transaction began, effectively undoing any partial changes that may compromise data integrity. Together, commits and rollbacks form the foundation for maintaining a consistent and reliable state within the database, making them essential for ensuring the integrity of the data.

Other methods, while important for overall data quality and security, do not directly address the transactional integrity in the same manner. Database integrity checks are more focused on assessing the overall consistency of the data and identifying existing anomalies, while validation checks ensure that the data input meets specific requirements. Input controls help prevent errors at the entry point but do not manage the state of the database during concurrent transactions, making commits and rollbacks the most effective and direct
