Understanding the dbt Semantic Layer architecture

What is the dbt Semantic Layer architecture?

The Semantic Layer acts as a translator between data and language, allowing end users to access metrics and their contextual information wherever they may be. The Semantic Layer introduces a new approach to defining the edges of the graph, with entities allowing the edges of the graph to be inferred, resulting in greatly reduced logic to maintain.

The Semantic Layer serves as a bridge between data and language, facilitating user access to metrics and related information.
It introduces a novel method for defining the edges of the graph, using entities to infer these edges.
This results in significantly lower logic maintenance requirements.

What are the advantages of the dbt Semantic Layer architecture?

The advantages include: providing a consistent definition of metrics across the organization, flexibility in consumption endpoints, reusability of metrics, reduced cost/compute, governance & auditing support, and reduced data inequality. The Semantic Layer also integrates with MetricFlow, supports major platforms like Snowflake, BigQuery, Databricks, Redshift, and Starburst, offers optimized query plans and SQL generation, introduces more complex metric types, and provides a GraphQL API.
