ER diagrams appear on the rightmost tab of the Database Object Editor:
Entity Relation Diagrams (ERD) are graphic presentations of database entities and the relations between them. DBeaver allows you to view the diagrams of existing tables and whole database schemas, see Database Structure Diagrams. DB also allows the creation of custom diagrams, see
By default DBeaver uses IDEF1X notation.
Both types of diagrams provide the same tools to adjust their view and structure. They can be printed and exported to image file formats.
Selection of Elements in Diagrams
You can use one of the two tools to select elements in diagrams:
Select – supports both, single and multi-select modes. To select a single element (table, connection, entity inside a table) in a diagram, just click that element. To select multiple elements, similar to using the Marquee tool, click outside the first element and draw until all elements you need are in focus:
NOTE: All changes to existing database schemas cannot be saved and are intended for exploration purposes only.
You can do the following structural changes in the diagrams.
- Add new tables to a diagram by drag-n-dropping them onto the diagram field from the Database Navigator.
