Medallion Architecture and Scalable Data Modeling in Microsoft Fabric
Bronze, Silver, and Gold layers in Fabric for scalable analytics and data quality.
The medallion pattern organizes data into Bronze (raw), Silver (cleaned and validated), and Gold (business-ready) layers. In Microsoft Fabric, you implement this using a lakehouse or warehouse, with notebooks or Dataflows for ingestion and transformation.
Why it helps
Bronze preserves the source as-is for audit and replay. Silver applies cleansing, deduplication, and conformed types. Gold holds star schemas or aggregates for reporting and analytics. This separation improves trust, reuse, and governance.
In Fabric, use OneLake as the single store, Delta tables for Silver and Gold, and Power BI semantic models or DirectLake on Gold for fast reporting.
