There is a table with all Drupal 8 core mappings from the issue where they
were committed <https://drupal.org/node/1784234>. Other than those, the
mappings would not likely happen in 3rd party extensions but would instead
be done on a site by site basis.

The thing that makes Drupal unique is that it gives site builders a very
flexible UI for creating their database schema by attaching fields to
content types. Because of this, the domain model for most Drupal sites is
quite custom and is not provided by an extension.
