Explanation
In the Databricks Lakehouse architecture, data flows through different layers with increasing levels of refinement:
- Bronze Layer: Raw data ingestion
- Silver Layer: Cleaned, validated, and enriched data
- Gold Layer: Business-level aggregated data ready for consumption
Why option A is correct:
- Gold tables typically contain aggregated, summarized, and business-ready data
- They are designed for consumption by business users, analysts, and reporting tools
- Aggregations in Gold tables include metrics like daily sales totals, customer lifetime value, or other business KPIs
Why other options are incorrect:
- B: Both Silver and Gold tables contain valuable data, but Gold tables are specifically structured for business consumption
- C: Gold tables contain a MORE refined view of data than Silver tables (not less)
- D: Gold tables typically contain LESS data than Silver tables because they store aggregated/summarized data
- E: Both layers should contain truthful data; Silver tables contain validated/cleaned data, while Gold tables contain aggregated business metrics
The key distinction is that Gold tables represent the final, business-ready layer with aggregated data optimized for consumption, while Silver tables contain cleaned and enriched data that serves as the foundation for creating Gold tables.
