3.1.1 Abstract Data Model
A Group Policy server's storage of the policy administration data can be defined as follows.
The Group Policy server models a list of deployed applications stored within a GPO. Each deployed software item has a set of attributes that define what the client does with the software (that is, install, remove, or reinstall), and how it performs the operation.
The administrative plug-in simply has a UI that can manipulate corresponding settings and push them to the server. The administrative plug-in can be modeled in the manner specified in the subsections that follow.
