Write Note on Partitioning?

Partitioning of architecture is an important concept. What we basically want to do is distribute the responsibilities to different subsystems so that we get a software system which is easy to maintain. Partitioning results in a system that suffers from fewer side effects. This ultimately means that we get a system that is easier to test and extend and hence is easier to maintain.

Partitioning of architecture may be “horizontal” and/or “vertical”.

In the horizontal partitioning we define separate branches of the module hierarchy for each major function and control modules are used to coordinate communication between functions. Vertical partitioning divides the application from a decision making perspective. The architecture is partitioned in horizontal layers so that decision making and work are stratified with the decision making modules residing at the top of the hierarchy and worker coming at the bottom. This partitioning is also known as factoring.
