The dbt Semantic Layer is a product by dbt Labs that allows organisations to centrally define metrics to ensure consistent access in downstream data applications. It can query data dynamically and automatically handles joins through sophisticated SQL generation. You can find more documentation on the dbt Semantic Layer here.

Use the dbt Semantic Layer connector in Tableau to make a live connection into the dbt Semantic Layer, query the metrics defined in code, and create and publish dashboards with trusted data from the source of truth. Using the dbt Semantic Layer connector for Tableau, you can reduce your dependencies on data extracts without compromising governance and create a simplified interface in Tableau by moving more of your business logic into code.
