What is the role of mechanisms in ensuring recoverability of a database?

• A. To provide real-time analytics
• B. To guarantee data integrity during transactions
• C. To enable data to be restored after a failure
• D. To facilitate user access to databases

Answer: (C)

The role of mechanisms in ensuring recoverability of a database is fundamentally about enabling data to be restored after a failure. This involves employing various strategies and tools that work to protect and recover data in case of a system crash, corruption, or other types of failures. These mechanisms can include backups, logging, and replication processes that capture changes to the database, allowing for the database state to be returned to a previous point in time or for lost transactions to be reapplied. When a failure occurs, these mechanisms are vital because they ensure that there is a reliable way to restore the database to a stable state, minimizing data loss and downtime. This is critical for maintaining not just business continuity, but also for complying with data governance and regulatory requirements that necessitate the protection of data assets. Real-time analytics focuses on providing immediate insights from data rather than ensuring recoverability, while guaranteeing data integrity during transactions is more associated with the correctness and accuracy of data state during operational processes. Facilitating user access to databases pertains to usability and access control, which doesn't directly address the need for recovery in the event of system failures.
