How does data lineage tracking work in modern data catalog platforms?

Data lineage captures source-to-consumption relationships: from ingestion (Fivetran, Airbyte) through transformation (dbt, Spark) to serving (BI tools). Platforms like OpenLineage (open standard), Marquez, and Atlan use column-level lineage APIs to track how data changes at each stage, enabling root-cause analysis for data quality issues.

What open-source data catalog alternatives exist for cost-conscious enterprises?

Apache Atlas provides open-source data governance for Hadoop/Hive ecosystems. DataHub (LinkedIn) and OpenMetadata are modern open-source data catalogs supporting 50+ connectors, lineage tracking, and metadata APIs. These require self-hosting but offer lower licensing costs than commercial platforms like Collibra or Informatica.

How should enterprises implement a data governance framework alongside a data catalog?

Effective data governance programs define: data ownership (who is responsible per domain), data classification (public, internal, confidential, regulated), data steward responsibilities, policy enforcement points (masking, access control), SLAs for data quality and freshness, and quarterly data governance council reviews — all anchored to the data catalog as the system of record.
