Q. What is the difference between module coupling and module collection? List different types of coupling and cohesion.
Ans: Cohesion is the property of a single module as well as can be described as glue that keeps the data elements within a single module together. While defining we should aim for high cohesion. Diverse kinds of cohesion are:
1) Coincidental Cohesion
2) Logical Cohesion
3) Temporal Cohesion
4) Communicational Cohesion
5) Sequential Cohesion
6) Functional Cohesion
7) Procedural Cohesion
Coupling alternatively is the measure of dependence among modules. A designer must try for minimum coupling. Different types of coupling are:
1) Content Coupling
2) Common Coupling
3) Control Coupling
4) Stamp Coupling
5) Data Coupling
The sequence of testing is: a) Unit testing: b) Integration testing: Alpha Testing- Beta testing Acceptance Testing
