Our model consists of just a few tables. Imagine a scenario where we have many more sources of data and a much more complex dimensional model. We could also have an intermediate zone between the raw data and the dimensional model that follows the Data Vault 2.0 principles. Would it not be useful, if we had the inputs, transformations and outputs documented somehow? dbt allows us to generate documentation from its configuration files:
dbt docs generate
This will produce HTML files in ./target directory.
You can start your own server to browse the documentation. The following command will start a server and open up a browser tab with the docs' landing page:
dbt docs serve
