A diagram is a graphical representation of the tables and their relations with each other in a system, i.e., the structure of your data based on the business processes.

**To see** the model of your application, click the **Diagram** tab of the Data model editor.

Optionally, reposition the tables, zoom or fit the view, toggle interactivity, and show or hide specific tables so you can focus exactly on what you need to see.
