I have read in OOPS that during Analysis stage of doing Functional model we draw DFDs but no where in UML it talks about DFD so does UML contain only the Object and Dynamic model of OOPS and not Functional model

Hello,

Do you need to keep stuck to UML diagram if they don't exacly fill your needs and if you know some other aproach ? I think you are wasting time trying to use UML if it don't fit.

You may try to see http://www.agilemodeling.com/ and particulary http://www.agilemodeling.com/essays/agileModelingRUP.htm

regards

Sébastien

Functions are just "behavior" (output for a given input), and behavior has static and dynamic aspects, and UML has static and dynamic models for behavior.

There IS a programming paradigm, "functional programming" (a la ML or pure LISP) where there are no "side effects", but that is different than the Object Oriented Programming paradigm.
