Figure 75: Import/Update Architecture

The Abstract Data Model (ADM) is an XML file that contains configuration data for all
objects in a specific domain. The ADM is stored in the GUI Server, but you do not access
the ADM directly. When you create, update, or import a device, the GUI Server edits the
ADM to reflect the changes. The Management console uses the ADM to determine the
current options, fields, screens, and data range to display in the UI for each object.
A Data Model (DM) is an XML file that contains configuration data for an individual device.
The DM is stored in the Device Server. When you create, update, or import a device, the
GUI Server edits the ADM to reflect the changes, then translates that information to the
DM.

Data Model Schema

The structure of the ADM and DM is determined by the Data Model (DM) schema. The
DM schema reads from a device capability file to determine the supported features for
the ScreenOS version that is running on the managed devices. A device capability file
lists the fields and attributes that a specific ScreenOS version supports.
Your network may contain similar security devices that are running different ScreenOS
versions. For example, a NetScreen-5XT may run ScreenOS 5.x, which supports the
Routing Information Protocol (RIP), while another NetScreen-5XT runs ScreenOS 4.0.0r2,
