Silver table is the step of reducing and refining data after raw data was imported into bronze table. Gold table would be the last step where data aggregation is applied.
Cannot be D. If raw data are clean enough already and have no aggregations or other functions before to be in the silver table, there will be the same amount of data both side. A seems to be a better answer because from raw you will have more chance to make at least one transformation to refine data.
D. Silver tables contain less data than Bronze tables.
This is because Silver tables are typically more refined and processed versions of the raw data found in Bronze tables. Bronze tables often contain raw, unprocessed data, while Silver tables contain cleaned, filtered, or aggregated data. Therefore, Silver tables usually contain a subset or a refined version of the data in the Bronze tables, leading to less overall data in the Silver tables.
