Which layer holds raw data as it arrived in a medallion design?
Why B is the answer
Bronze
Bronze is raw, silver is cleaned, and gold is ready for reporting.
In detail
- Bronze holds raw data as it arrived.
- Keeping raw data lets you rebuild later layers.
Use case
An illustrative scenario, not a real incident.
A team keeps supplier files untouched in bronze, cleans them in silver, and publishes monthly totals in gold.
