Coupling (computer programming)

In software engineering, coupling is the degree of interdependence between software modules; a measure of how closely connected two routines or modules are;^[1] the strength of the relationships between modules.^[2] Coupling isn't binary but it's multi-dimensional. ^[3]

Coupling is usually contrasted with cohesion. Low coupling often correlates with high cohesion, and vice versa. Low coupling is often thought to be a sign of a well-structured computer system and a good design, and when combined with high cohesion, supports the general goals of high readability and maintainability.^{[citation needed]}
