By fusing these components seamlessly, organisations can facilitate efficient storage, processing, and analysis of vast and varied datasets, setting the stage for data-driven decision-making.

The medallion architecture is a data design pattern used to logically organise data in a lakehouse, with the goal of incrementally and progressively improving the structure and quality of data as it flows through each layer of the architecture. The architecture describes a series of data layers that denote the quality of data stored in the lakehouse. It is highly recommended, by Microsoft and Databricks, to take a multi-layered approach to building a single source of truth (golden source) for enterprise data products. This architecture guarantees atomicity, consistency, isolation, and durability as data passes through multiple layers of validations and transformations before being stored in a layout optimised for efficient analytics. The terms bronze (raw), silver (validated), and gold (enriched) describe the quality of the data in each of these layers.
