HTML report / online ER diagram

Here you can find a preview of ER diagram created by loading the database structure from installed Drupal version 10.0.9. Target database is MariaDB with InnoDB default engine.

When you click on a database table in the online ER diagram, a new window opens where you can see the details of the table, including defined indexes and other details, as well as well-written descriptions written by the Drupal CMS authors.

This is a nice example of how useful descriptions defined for database tables or table columns are.

Like many other open source systems, database functions, table triggers and other database objects are missing here. The visualization includes database tables, with some of them colored to indicate a group of tables that are focused on a particular area of the database design.
