Semantic Layer Course: Metrics, Entities, Measures, and Dimensions

Learn semantic layer fundamentals: entities, measures, dimensions, metrics, semantic graphs, and how governed metrics serve BI and AI tools.

A semantic layer centralizes business meaning so BI tools, embedded analytics, spreadsheets, and AI systems all use the same governed definitions. This course teaches the concepts with small ecommerce examples before introducing MetricFlow and the dbt Semantic Layer.
