Built on Databricks Community Edition, pulling CPI data from the FRED API for Brazil, Japan, UK, and USA. Bronze stores the raw API response. Silver removes duplicates and cuts each series to a shared date range so all four countries cover the same window. Gold maps FRED's series IDs to country names and builds the final table. The CSV here came straight out of that Gold layer.
