Explanation
In the Databricks Medallion Architecture:
Silver Layer: Contains cleaned, enriched, and validated data. This layer has data that has been transformed from the raw Bronze layer but is not yet fully optimized for business consumption.
Gold Layer: Contains highly refined, aggregated, and business-ready data. This layer is optimized for reporting and analytics with:
- More transformations applied
- Aggregations and summaries
- De-normalized data models
- Read-optimized structures
- Fewer joins needed for queries
The key distinction is that Gold tables undergo more transformations and are specifically designed for business consumption, which often involves aggregations, summaries, and de-normalization for performance. While both layers contain valuable and truthful data, the Gold layer is specifically structured for reporting purposes with more transformations including aggregations.
Why other options are incorrect:
- B: Both layers contain valuable data - the value is in how it's structured, not the inherent value
- C: Gold tables contain MORE refined views, not less refined
- D: Gold tables often contain LESS data due to aggregations and summaries
- E: Both layers should contain truthful data after cleaning and validation
