This page lists a number of Subject Area Data Models.
They represent 'stripped-down' Models which contain the basics for a specific application area.
Subject Area Data Models are major functional areas within an orgnaisation that can be used to
define the scope for smaller Data Models that can be integrated to define a comprehensive
Data Model.

They are 'Canonical' Models that can be used as a common point of reference and a way of
exchanging data between more detailed Models.

Step-by-Step Tutorials showing how Subject Areas can be combined as part of a Top-Level Model are available for Services for Certification and Tracking Shipping and a smaller one for Gym Management.

"**John Giles" indicates that John has identified the Data Model as a Design Pattern in his 'Nimble Elephant' book.
