How does dbt handle model names when models are inside directories?

dbt uses the folder path as part of the model's unique identifier. For example, a model in 'models/sales/orders.sql' will have the name 'sales.orders'. This helps avoid name conflicts and clarifies model relationships.

intermediate

Can you configure model properties differently for models in different directories?

Yes! You can use 'dbt_project.yml' to set configurations for all models in a directory. For example, you can set materializations or tags for every model inside a specific folder, making management easier.
