The database diagram was created by reverse engineering the database structure from locally installed OpenCart version The target database type was MariaDB with InnoDB default engine.

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

The database structure is relatively simple and like in many other open source systems, database functions, table triggers and other database objects are not defined.
