What does data integrity mean and why is it critical?

• A. Timeliness of Data
• B. Privacy of Data
• C. Accuracy, Consistency, and Completeness of Data
• D. Data Encryption

Answer: (C)

Data integrity means keeping data accurate, consistent, and complete throughout its life. When data is accurate, its values reflect the true state they’re meant to represent. When it’s consistent, the same data point shows the same meaning across different systems or records. When it’s complete, nothing essential is missing that would change the interpretation of the data. Together, these traits make data trustworthy and usable for analysis, reporting, and decision-making. This is why data integrity is critical: decisions, operations, and insights rely on data you can trust. If data is wrong, inconsistent, or incomplete, reports can mislead, processes can fail, and compliance or safety could be at risk. Ensuring integrity prevents those problems by making sure data remains correct and coherent as it moves and evolves. Other options touch on important data aspects but do not define integrity itself. Timeliness is about data being up-to-date, privacy concerns protect individuals’ information, and encryption safeguards against unauthorized access. Each matters, but the meaningful reliability of data lies in its accuracy, consistency, and completeness. Maintaining integrity involves validation rules, checksums or reconciliations, audit trails, and good data governance so errors are caught and corrected, and records can be trusted over time.
