HTML report / online ERD

The online entity relationship diagram (online ERD) was created by reverse engineering the database structure from locally installed Joomla! version 4.3.2. No Joomla! extensions were installed and the target database was MariaDB with InnoDB default engine.

How to use the simple ERD: click on a db table in the online ERD. 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.
