Verification and Validation in Data Entry

* Verification ensures that data matches the original source, while validation checks data against rules to ensure correctness.

Verification confirms that the entered data matches the original source document, using methods like double entry, proofreading, and data reconciliation. Validation checks if the entered data meets specific criteria and conforms to established rules, using methods like data type checks, range checks, check digit verification, and lookup checks. Verification focuses on accuracy against the source, while validation focuses on data integrity and adherence to rules. Verification often involves manual checks, while validation may involve automated checks.
