What is data lineage and why is it important in data governance?

• A. The final data format used in reports
• B. The storage location of backups
• C. The access controls for data assets
• D. The origin and transformations of data as it moves through systems; important for traceability, quality, and compliance

Answer: (D)

Data lineage is about tracing the origin and the journey of data as it moves through systems, including every transformation it undergoes from source to final use. In data governance, this provenance matters because it gives you traceability: you can see where a data value came from, what steps altered it, and where it ends up. This supports data quality by letting you identify where errors were introduced and how they propagate, and it supports compliance by providing an auditable record of data handling for regulatory and governance requirements. It also enables impact analysis—when a data source or rule changes, you can see which reports and decisions are affected. This concept isn’t about the final report format, where backups are stored, or who has access to data; those are separate concerns like presentation, backup management, and security controls.
