Question
Which layer of the medallion architecture is most commonly used by data analysts?
Options
- ADashboards
- BGold
- CBronze
- DSilver
Explanation
Gold is correct because it represents the business-ready layer of the medallion architecture - data that has already been cleaned, transformed, and aggregated into domain-specific models (e.g., fact tables, KPIs, summary views). Data analysts consume this layer directly for reporting, dashboards, and ad hoc analysis without needing to worry about raw data quality or transformation logic.
Why the distractors are wrong:
- A (Dashboards): Dashboards are not a layer of the medallion architecture at all - they are a tool built on top of it, often consuming Gold layer data.
- C (Bronze): Bronze is the raw ingestion layer - unvalidated, unstructured data straight from source systems. It's used by data engineers, not analysts.
- D (Silver): Silver is the cleansed and conformed layer - useful for engineers and some data scientists building models, but it still requires further aggregation before most analysts would use it.
Memory tip: Think of metals by value - Bronze (raw/cheap), Silver (refined), Gold (most valuable/ready to use). Analysts want the most valuable, ready-to-use data, so they live in Gold.
