What is the process called that verifies the accuracy and reliability of data in a warehouse?

• A. Data cleansing
• B. Information governance
• C. Information validation
• D. Quality assurance

Answer: (C)

Information validation focuses on applying rules and checks to ensure data is accurate and reliable before it is used in the warehouse. This means verifying that data values follow expected formats, fall within valid ranges, maintain consistent relationships (like referential integrity), and align with business rules. By validating data, you catch and flag inconsistencies or errors early, so the data feeding reports and analytics is trustworthy. Data cleansing would involve fixing or removing bad data after it's found; information governance is the overarching policy framework for data management; quality assurance is a broader set of practices ensuring processes and products meet quality standards, not limited to data validation alone.
