Medallion Architecture

A medallion architecture is a data design pattern used to logically organize data in a lakehouse, with the goal of incrementally and progressively improving the structure and quality of data as it flows through each layer of the architecture (from Bronze ⇒ Silver ⇒ Gold layer tables). Medallion architectures are sometimes also referred to as "multi-hop" architectures.

Bronze layer

Raw data.

Silver layer

Cleansed and conformed data.

Gold layer

Curated business-level tables.
