Database diagrams graphically show the structure of the database and relations between database objects. You can generate a diagram for a data source, a schema, or a table. To create relations between database objects, consider using primary and foreign keys.
You can save the generated diagrams in two formats: UML and PNG. The UML format is an internal format developed specifically for JetBrains Rider. It is not supported by other products. If you want to share the created diagram, consider using PNG.
Also, you can build execution plans. Execution plan is a set of steps that were used to access data in a database. JetBrains Rider supports two types of execution plans:
Explain Plan: the result is shown in a mixed tree and table format on a dedicated Plan tab. You can click the Show Visualization icon () to create a diagram that visualizes the query execution.
Explain Plan (Raw): the result is shown in a table format.
Pan and zoom the diagram
To pan and zoom the diagram, use your touchpad, scroll bars or the mouse wheel for vertical scrolling and Shift + mouse wheel for horizontal scrolling. You can also use Shift + mouse wheel for zooming.
To use the magnifier tool, keep the Alt key pressed, and hover your mouse pointer over the desired areas of the diagram. Use the mouse wheel to extra zoom the diagram area within magnifier tool.
