Data Lineage: The Foundation of Enterprise Data Infrastructure (2026 Guide)

Data lineage tracks every data asset from origin to consumption, covering sources, transformations, pipelines, and destinations. Column-level lineage is now the minimum viable standard for enterprise use cases, enabling faster root-cause analysis, confident impact analysis before schema changes, and regulatory compliance (BCBS 239, GDPR, SOX). Lineage also underpins AI/ML readiness by providing auditable provenance chains for feature stores and RAG pipelines. A six-step implementation guide covers auditing pipeline coverage, prioritizing column-level granularity, automating capture, connecting lineage to observability, exposing business lineage to non-technical stakeholders, and integrating lineage with governance workflows.
