Architecture of QTP framework

[ramesh]

Hi All,
What I know about framework are:
Module Driven FW: This helps testscripts to share reusable code(functions).
Keyword Driven FW: This helps to create sharing descriptions of AUT objects in multiple trestscripts.
Data Driven FW:Help us to Use same script for more than one data for multiple times
But in interview i was asked the architecture of different framework with diagram.
Can anyone please explain the architecture of QTP frameworks with proper diagram.

Thanks,
Ramesh Ch Tulal
