Q. Illustrate Partitioning in stepwise refinement?
Problems are frequently too large and complex to be understood as a whole. Therefore we tend to partition such problems into parts that can be easily understood and establish interfaces between the parts thus that overall function can be accomplished.
Partitioning decayed a problem into its constituent parts. We set up a hierarchical representation of function or information and then partition the uppermost element by:-
1) Exposing increasing detail by moving upright in the hierarchy or
2) Functionality decomposing the problem by affecting horizontally in the hierarchy.
