Medallion data architecture is a way of splitting the ingestion and processing of data into three stages: bronze, silver, and gold.Â
- In the bronze stage, ingested data is stored in its unaltered form.Â
- The silver stage attempts to fix problems in the bronze data and augment it by linking it with other data, producing a more usable version.
- The gold stage takes the silver data and summarises it, along with any other processing needed to make the data ready for consumption by downstream processes.
