A Medaillion Architecture is used to store data in a data lakehouse structure through three layers: bronze, silver and gold. The goal is to gradually raise the data structure & data quality as the data moves from the bronze layer to the gold layer:
- Bronze: raw & unprocessed data taken from the source.
- Silver: data has been checked for quality & reliability and converted into a naming convention recognizable to the organization.
- Gold: data is optimized to be used in reports (facts & dimensions)
One of the advantages of this architecture is that i.c.w. a data lakehouse solution, both Data Scientists and Data Analysts can use the processed data.
A good comprehensive description in English of the Medailliion architecture can be found on a blog by Piethein Strengholt.
