Medallion data architecture is designed to establish a consistent path from data to business data, which is predictable. Data flows through different stages with individual processing steps instead of a single complex pipeline. This can help to enhance data quality, aid in debugging and enhance data governance. It also gives the opportunity for the use of various teams to work with the layer they need. For instance, engineers might only interact with raw and cleaned data and analysts could only meet with “curated” data without having to go through each step of the data transformation.
