Medallion Architecture organizes data into three distinct layers—Bronze, Silver, and Gold—enhancing data quality and usability as it progresses through the system. Originating from Databricks' Lakehouse vision, this design pattern emphasizes the importance of structured and unstructured data integration for effective decision-making.

The author critiques the Medallion Architecture promoted by Databricks, arguing that it is merely marketing jargon that confuses data modeling concepts. They believe it misleads new data engineers and pushes unnecessary complexity, advocating instead for traditional data modeling practices that have proven effective over decades.
