Answer-first summary for fast verification
Answer: To refine the data through cleaning, deduplication, and enrichment, ensuring it is prepared for downstream analytics and processing.
The **Silver layer** represents a validated, cleansed, and enriched version of the data. While the Bronze layer preserves the raw state of the data, the transition to Silver involves critical data engineering tasks such as **schema enforcement, deduplication, and data normalization**. This ensures that downstream consumers (including the Gold layer or ad-hoc analytical queries) have access to high-quality, reliable datasets.
