Structure view
Switch a table to its Structure tab to see how it is built:- Columns - name, type, nullability, default, and keys.
- Indexes - including uniqueness.
- Foreign keys - relationships to other tables.
- Triggers - where the engine supports them.

ER diagram
Open the Diagram tab to see your tables and their relationships as an entity-relationship diagram, a quick way to understand an unfamiliar schema.
Viewing the structure and the diagram is free. Exporting the diagram (PNG, SVG, or DBML) is a PRO feature.
