What is information validation?

• A. Process to ensure information in data warehouse is correct, reliable and consistent
• B. Process to ensure information in data warehouse is from the correct facility
• C. Process to ensure information in data warehouse is from the correct time submission
• D. Process to ensure information in data warehouse is correct and from the correct charts

Answer: (A)

Information validation is the process of checking data to ensure it is correct, reliable, and consistent before it is used in the data warehouse. It involves verifying accuracy against trusted sources, ensuring completeness of key fields, and enforcing consistency across different data sources and over time. In a data warehouse, validation is a core part of the ETL process, catching errors, mismatches, and rule violations so reports and analyses are trustworthy. While knowing where data comes from or when it was submitted can be relevant to data quality, validation itself focuses on the data values meeting quality standards rather than just their source or timing.
