Açıklaması şöyle
Medallion architecture is a data design pattern that organizes data into three layers:Bronze Layer (Raw):
- Data ingested in its original format
- Minimal transformation
- Append-only historical record
- No data quality enforcement
Silver Layer (Refined):
- Cleaned and conformed data
- Schema enforced
- Deduplicated
- Validated
- Still fairly granular
Gold Layer (Curated):
- Business-level aggregations
- Denormalized for consumption
- Optimized for specific use cases
- Analytics-ready
Origin: Popularized by Databricks around 2019-2020 as part of the lakehouse pattern.
