Understanding Semantic Models and Data Lake House Layers

The Dashboard Effect

In this episode of The Dashboard Effect Podcast, host Brick Thompson and Blue Margin’s Director of Solutions, Landon Ochs, dive into the nuances of semantic models and the bronze, silver, and gold layers within a data lake house. They explain the roles of each layer, how data is transformed at each stage, and why collaboration with business users is essential for accurate and actionable BI reporting.
Through this episode, you'll learn why different layers serve different purposes—from storing raw data to pre-joining tables for efficiency to creating finalized data ready for reporting. They also discuss how the semantic model is designed to simplify complex data relationships, making reporting easier for non-technical users.
