Online ER Diagram / database design

The database design was created by loading the database structure from a remotely hosted Moodle version 4-0-2. The target database was MariaDB. The diagram contains 468 tables. The amount of tables and metadata might affect the performance of the diagram/report, that’s why it is recommended to use Luna Modeler for better user experience.

How to use the ER diagram: click on a db table in the online ER Diagram. A new window opens – and in the window you can view the details of the table, including how indexes are defined and other details of the selected MariaDB table.

The database structure doesn’t include relationships and like in many other open source systems, database functions, table triggers and other database objects are not specified.
