Medallion Architecture
A multi-hop data design pattern that incrementally refines data quality through Bronze, Silver and Gold layers.
BRONZE
Raw, ingested data in native format. Full fidelity for reprocessing and audit.
SILVER
Cleaned, validated, and conformed. Creates usable enterprise datasets.
GOLD
Curated, aggregated data optimized for BI, ML, and consumption.
Origin: First coined by Databricks, now embedded in Microsoft Fabric
