Django-Oscar Entity Relationship Diagrams

A complete set of standard entity relationship diagrams for django-oscar webapps has at least 161 tables. This is how I counted them:

Shell
$ psql -U postgres -h localhost -d frobshop \
  -tc "select count(*) as tables from information_schema.tables where table_type = 'BASE TABLE';"
161

I used Dbeaver to create the following entity relationship diagrams of the django-oscar schema. There were too many table to examine in one diagram, so I examined them piecemeal.

Update 2021-03-28: When I first saw the table names I could not understand the naming convention. After having spent some time looking at the source code and playing with the software, I now believe that a table name is constructed from a Django app name, concatenated with the corresponding app model's class name, like this: {appname}_{classname}. If a class field joins to another class, the naming convention becomes: {appname}_{classname}{join_table_name}

The remainder of this article shows most of the 161 django-oscar tables. Some tables are shown more than once in the interest of clarity.
