Which data-integrity concept best supports reviewing the evolution of records?

• A. Accuracy
• B. Completeness
• C. Audit trails
• D. Security

Answer: (C)

Tracking how a record changes over time requires a reliable history that shows each modification. Audit trails are designed to capture that history, recording every change along with who made it, when, and, often, the before-and-after values. This makes it possible to review the evolution of records, verify what happened, and reconstruct past states if needed.

Other concepts don't provide that longitudinal view. Accuracy concerns correctness at a point in time, not how the data got there. Completeness ensures all required data is present, but not how it evolved. Security protects data from unauthorized access or alteration, but without a log of changes, you can’t trace the evolution itself.
