Need help on this, thanks!

UML has no provision for developing data flow diagrams. It does, however, provide a set of modeling objects that can be used to create activity diagrams. The Unified Process is so adamantly opposed to DFDs that it specifically warns against their use, insisting that DFDs lead to procedurally conceived, and therefore inferior, programs. What is your position on this issue? Elaborate. Support your position with an example of a hypothetical system that could not be built without accommodation of the basic points of your position.
