Coupling definition in software

Coupling is how much components depend on each other. Cohesion is a measure of how much the parts of a component belong to together. The two properties are inversely proportional. We lowered the coupling in our example by separating concerns between the sender and the receiver. We ended up pushing some of the logic embedded in the two classes up into main. In production code, you would replace main with a formal class called something like a dispatcher or a manager.

You might even push the list of receivers into it. NDepend can help you improve your code by showing you opportunities to remove tight couplings and increase cohesion. Efferent coupling shows types that rely heavily on others. This metric highlights design problems since a type that interacts with a large number of objects has too many concerns.

Afferent coupling shows methods that are used heavily in a program. Coupling affects your ability to modify and maintain your code. Also, changes tend to ripple across many objects. Take a look at your code and see if you can find areas where you can lower coupling and increase cohesion.

In this article, I have tried to explain the data coupling and control coupling with simple examples.

This is one of the poorly understood concept in the aviation software in the context of DOC. Data provided was useful to understand the concept but more elaborate explanation could help an engineer to perform the DCCC analysis for a software project. Your email address will not be published.
