Which maintenance process is most likely to help identify integrity issues in a database experiencing crashes and slow queries?

• A. Data migration
• B. Data corruption checks
• C. System restoration
• D. Load balancing

Answer: (B)

Identifying integrity issues in a database that is experiencing crashes and slow queries is crucial for maintaining data reliability and performance. The process that directly targets this concern is data corruption checks.

Data corruption checks involve running diagnostic tools or utilities to verify the integrity of the data stored within the database. These checks can uncover inconsistencies, corruption, or anomalies in the data, which are often the root causes of system crashes and performance issues. By routinely conducting these checks, database administrators can identify problems before they lead to larger issues, ensuring that the data remains reliable and accurate.

On the other hand, data migration focuses on moving data from one system to another and does not inherently address integrity concerns of the existing database. System restoration involves reverting to a previous state of the database, which might not fix underlying integrity problems. Load balancing is related to distributing workloads across multiple resources to optimize resource use, which does not specifically help identify issues within the data itself. Therefore, data corruption checks are the most relevant and effective method for diagnosing integrity issues in this scenario.
