Rethinking Data Layers: When Medallion Architecture Isn’t Enough

Medallion Architecture's three-layer model (bronze, silver, gold) often falls short for large-scale businesses. Challenges like hidden crucial datasets and irregular updates necessitate more nuanced layers. Key considerations include granular pipeline tracking, regulatory compliance, data science needs, optimized reporting, data quality checks, and schema validation. Adapt layers based on organizational requirements, employing techniques such as raw data storage, schema validation, and data masking for better data integrity and security.
