The data model viewer provides you with an overview of the data structure of the app. You can preview data in the tables and fields in the data model viewer.
In the data model viewer, each data table is represented by a box, with the table name as title and with all fields in the table listed. Table associations are shown with lines, with a dotted line indicating a circular reference. When you select a table or a field, the highlighting of associations instantly gives you a picture of how fields and tables are related.
You can change the zoom level by clicking Y, Z or using the slider. Click ü to restore the zoom level to 1:1.
