Modular Design
Coupling
Coupling is a measure of the interdependence among
software modules.
For unrelated modules, high coupling is bad, low coupling is good.
For closely related modules, high coupling is good, low coupling is bad.
No direct coupling
Data coupling (by passing parameters)
Stamp coupling (by passing structures or pointers)
Control coupling (using flag to control a submodule)
Common coupling (using common area or global variables)
Content coupling
