differenciate between coupling and cohesion
Coupling
1)Coupling is the measure of interdependence among models.
2)Modules are dependent on each other such that changes to one module affects other modules.
3)A high degree of Coupling must be avoided while designing.
4)In case of High Coupling , it is very difficult to understand the modules.
5)In case of High Coupling ,we can not reuse the modules.
Cohesion
1)Cohesion is the measure of functional grouping of elements within a single module
2)Modules are dependent on each other such that changes to one module does not affects other modules directly.
3)A high degree of Coupling must be considered while designing.
4)In case of High Coupling , it is very easy to understand the modules.
5)In case of High Coupling ,we can easily reuse the modules.
