Which term describes the process of checking data accuracy before loading into a system?

Data validation is the process of checking data against defined rules and constraints to ensure it is accurate, complete, and consistent before it is loaded into a system. This gatekeeping step catches issues like incorrect formats, missing values, out-of-range numbers, or mismatched records, preventing bad data from entering the data store and causing downstream problems. Cleaning would be the act of fixing or removing bad data after it’s identified, rather than the initial check. Verification can refer to confirming correctness against a source or after processing, and auditing focuses on reviewing processes for compliance rather than the data’s accuracy itself.
