What role does metadata play in governance and understanding of data?

• A. Describes data definitions, lineage, quality, and usage
• B. Stores actual transactional data
• C. Controls access to data
• D. Encrypts data at rest

Answer: (A)

Metadata is information about data that makes governance and understanding possible. It describes what data means (definitions), where it comes from and how it moves (lineage), how trustworthy it is and where quality issues lie (quality), and how the data is used and who is responsible for it (usage and stewardship). By providing this context, metadata acts like a map and a quality ledger for the organization’s data, helping people find the right data, understand its meaning, assess its reliability, and enforce policies. It supports data catalogs, lineage tracing to see the impact of changes, and governance processes that require clear ownership and usage rules.

Storing actual transactional data isn’t metadata—that’s the data itself. Controlling access and encrypting data are security functions, not metadata’s primary governance role.
