Database diagrams
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 AppCode. 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. AppCode 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.

To create an execution plan, right-click a query in the editor and select Explain Plan. If you want to create a diagram for the query, click the Show Visualization icon (
).
