Section 2. Application design

Application design: Entity design

This tutorial uses an example based on a fictitious authentication subsystem for an

online content management system with the following capabilities:

log users into the system

authenticate users are in certain roles

allow user to be organized into groups to allow group operations

store user information like address and contact information

manage roles, users, groups

I picked this domain because most developers are familiar with it to some degree I

want to spend the content of this tutorial covering the technology rather the domain of

the example.
