Data Lineage

Definitions

1. The tracking of data's journey from source through transformations to final consumption — which systems produced it, what transformations were applied, and who consumed it. Essential for debugging data quality issues, regulatory compliance (GDPR, CCPA), and impact analysis when changing upstream schemas.

   In plain English: A map showing where data came from, how it was transformed, and where it ended up — like a family tree for data.

   Example: "Data lineage showed the revenue discrepancy originated in a currency conversion step three pipelines upstream."
