The YAML description: entries, the compiled SQL and the column types read from the database feed a documentation site. dbt 37,942 docs generate writes manifest.json (the project and its DAG) and catalog.json (the warehouse's columns); --static also bundles both into one static_index.html that opens from disk. dbt docs serve --port 32081 serves the same site locally.
Green source nodes feed staging views, which feed the dimensions and the fact table; the seed feeds dim_book, and the singular test reads both fct_sales and its source. dim_date stands alone because it reads no table. The pink nodes are the semantic models and metrics that A Shared Metric Set adds to the same project. Orchestration and Pipelines's Astronomer 149,584 Cosmos reads the project to turn each model and test into an Airflow 129 task.
