TOM or test object model is the object model that QTP uses 
to recognise objects in the application. Every object has a 
set of properties and attributes which QTP uses to perform 
operations. Also using these attributes in form of 
mandatory and assistive properties, QTP recognise the 
particular object

By using QTP Automation Object Model(AOM), we can virtually 
control every feature of QTP and we can use objects, 
properties and methods i.e
We can script such way that what add-ins should be loaded, 
which OR to load, test setting options, and even we can 
write a script that modifies the test object description 
properties in the Object Identification etc…

Using AOM we Can Automate The Quick Test Process .This AOM 
Supports Some methods and Properties Through Those Methods 
we can open the test ,select the addins,save the test 
finally close the test.

Hi All,
 Object model: object models mainly classified in to 
1. Object repository : interfaces between application & QTP
tool ( using physical properties Q T p identify object in
the window (or) page (or) application).
2. Object identification : here tester converts non-
standards object in to standard object.
3. Object Spy : Using this, tester can know the physical
properties of the object
