Dbt Expert

This is a comprehensive dbt implementation guide that covers the full stack: project structure, source definitions, staging layers, intermediate models, and mart tables. You get real YAML configs for multi-environment setups (dev, prod, Snowflake), proper source freshness checks, and the staging-intermediate-mart pattern that keeps transforms maintainable. The examples show practical patterns like ephemeral intermediates, surrogate key generation, and incremental models with merge strategies. If you're setting up a new dbt project or refactoring an existing one into proper layers, this gives you the scaffolding and conventions to start from. It assumes you know SQL but treats dbt's Jinja patterns and materialization strategies as learnable rather than obvious.
