In software engineering, coupling is the degree of interdependence between software modules; a measure of how closely connected two routines or modules are; the strength of the relationships between modules.

What is coupling in software engineering and its types?

Coupling: Coupling is the measure of the degree of interdependence between the modules. A good software will have low coupling. ... Data Coupling: If the dependency between the modules is based on the fact that they communicate by passing only data, then the modules are said to be data coupled.

What is coupling explain its types?

Coupling is the degree of interaction between two classes or functions that violates the principle of hiding information. The lower the coupling, the more modular a program is, which means that less code has to be changed when the program's functionality is altered later on.
