Getting Started with Metrics. No dependencies Loosely coupled-some dependencies Highly couples-many dependencies Stamp Coupling : Communicating via a data structure passed as a parameter.

The data structure holds more information than the recipient needs. Data Coupling : best Communicating via parameter passing. The parameters passed are only those that the recipient needs. No data coupling : independent modules. Summary COHESION COUPLING The measure of strength The measure of of the association of interdependence of one elements within a module module to another It is the degree to which It describes the the responsibility of a relationship between single component form a software components meaningful unit It is a property or It is a property of a characteristic of an collection of modules individual module Stepwise Refinement Open Door walk to door; reach for knob; open door; repeat until door opens turn knob clockwise; walk through; if knob doesn't turn, then close door.
