# Dependencies

This feature allows linking the tables that contain relationships, dependencies, like the tables orders and order_details. This way, it’s possible to delete a record in the table orders, and it automatically deletes all the details for that order as well. Below let’s see a practical example of this feature.

1. Firstly, you must define a new dependency. Then you must select the dependent table. Click on the button New Dependency to start.

1. You must inform the fields amount is related between both tables. In this example, we have only one field.
