Medallion Architecture is a modern data lakehouse framework with three layers: Bronze (raw data), Silver (cleansed data), and Gold (curated data for analytics). It’s designed for scalability, supporting batch and streaming data in cloud environments like Databricks. Bill Inmon advocates a top-down approach with a normalized enterprise data warehouse (EDW) for consistency, aligning with Medallion’s Bronze/Silver layers. Ralph Kimball promotes a bottom-up approach with denormalized star schemas in data marts, resembling Medallion’s Gold layer. Medallion blends elements of both, adapting them for big data and modern analytics. If you meant something specific by “medallion architecture,” please clarify for a more targeted response.
