Answer: To clean, deduplicate, and enrich the data to provide a 'refined' version ready for downstream analysis.
The **Silver layer** acts as the intermediate refinement stage in the Lakehouse. Its main purpose is to transform raw data from the Bronze layer by applying schemas, removing duplicates, and performing data enrichment. This ensures that the data is high-quality and reliable for downstream BI applications or further aggregation in the Gold layer.
