please explain me the exact automation frame work of QTP

Following are the possible automation frameworks in any good automation tool available in market today.

5 major frameworks:
Script Modularity, Library Architecture, Keyword Driven, Data Driven and Hybrid.

Script Modularity is when we create independent automation scripts for each of the functionality, feature etc of the application under test. The logically related scripts are grouped together into modules that can be reused from the main test program.

Library Architecture is when we create functions for most reused features / functionalities in the application under test. A single function library is created to cover all logically related validations of a functionality. Multiple such libraries along with the build-in test tool libraries are associated to the tests in this framework.

Keyword Driven framework is well known to all. This is when all the steps in an action are represented and recognized by keywords along with argument values either static or parameterized.

Data Driven framework is also well known to all. This is when we parameterize the test data input from either as keyboard input, from external/internal files or from application objects themselves.

Hybrid framework is of-course a right combination of the first 4 frameworks.
