difference between coupling and cohesion in software engineering ppt

Common CouplingĬommon Coupling consists of the modules that share the overall constraints in the midst of any two modules of the software system. Web development, programming languages, Software testing & othersĮvery software requirement specification documentation process should have a classification of these coupling between the dependent modules, whichever is applicable after a brief evaluation performed on the requirement provided by the client.

Start Your Free Software Development Course Based on these possible dependencies, the coupling in software engineering is classified into six different types of coupling. This resource can be a functional behavior, a common interface, a common field in a user interface, the data picked from a field and shared between two modules, a transaction shared between two modules, etc. Types of CouplingĬoupling between any two modules is identified from the number and types of resources that the modules share with other modules. The first step taken in the coupling process is to evaluate the association between the two modules and to define the functionally dependent areas in the modules. The name coupling is applied for this process, as it is typically deliberated between two modules at a time. It is used as an indicator of interdependency amongst the modules, and the lower the coupling value will be, the higher the quality of the software will be.

Introduction to Coupling in Software EngineeringĬoupling in Software Engineering is a part of Software Requirement Specification (SRS) documentation that is used to define the factors of dependency and independence of each module of the software with other modules.
