The medallion architecture (as noted in the following diagram) allows for flexible access and extendable data processing. The Bronze tables are for data ingestion and enable quick access (without the need for data modeling) to a single source of truth for incoming IoT and transactional events. As data flows to Silver tables, it becomes more refined and optimized for business intelligence and data science use cases through data transformations and feature engineering. The Bronze and Silver tables also act as Operational Data Store (ODS) style tables allowing for agile modifications and reproducibility of downstream tables. Deeper analysis is done on Gold tables where analysts are empowered to use their method of choice (PySpark, Koalas, SQL, BI, and Excel all enable business analytics at Relogix) to derive new insights and formulate queries.
