Module 6: Data Discovery and Metadata Management
- Deploy automated metadata extractors to catalog datasets across databases, data lakes, and BI tools.
- Integrate data lineage tracking from ingestion to reporting layers to support impact analysis and compliance audits.
- Configure business glossary terms in Apache Atlas and link them to technical assets for cross-functional alignment.
