In the Medallion Architecture, which layer contains curated, aggregated data for business reporting?

• A. Bronze
• B. Raw
• C. Silver
• D. Gold

Answer: (D)

Data is organized into layers that progressively refine and prepare data for different purposes. Bronze holds raw, uncurated records as they arrive. Silver cleans, deduplicates, and standardizes this data, making it usable for analysis. Gold is where you put curated, aggregated data tailored for business reporting—metrics, KPIs, and ready-to-consume datasets for dashboards. Since business reporting relies on summarized and curated information rather than raw detail, the Gold layer is the appropriate source. That's why the correct choice is Gold.
