Which of the following records is vital for ensuring system integrity?

Ensuring system integrity heavily relies on the completeness, accuracy, and timeliness of records. This is because system integrity depends on having reliable data that can be trusted for decision-making processes. When records are complete, they reflect all pertinent information; when they are accurate, they contain no errors or misinformation; and when they are timely, they are updated to reflect the most current information available.

Complete and accurate records help to prevent misinformation and ensure that users can make informed decisions based on reliable data. Timely updates ensure that the system reflects the latest information, which is crucial in situations like emergency responses where immediate and precise data is critical. In contexts like Enhanced 911 procedures, having complete, accurate, and timely information can directly affect the outcomes of critical incidents.

The other options, while relevant to the overall performance of a system, do not specifically address the core values of integrity in data management as effectively as completeness, accuracy, and timeliness do.
