Coupling (computer programming)
open-in-new
<p>In <a href="/facts/Software_engineering/KX6cE9kz">software engineering</a>, coupling is the degree of interdependence between software <a href="/facts/Modular_programming/sNoqKvRD">modules</a>, a measure of how closely connected two routines or modules are, and the strength of the relationships between modules. Coupling is not binary but multi-dimensional. </p> <p>Coupling is usually contrasted with <a href="/facts/Cohesion_(computer_science)/4hgqzcsf">cohesion</a>. <a href="/facts/Loose_coupling/uXRb4qBJ">Low coupling</a> often correlates with high cohesion, and vice versa. Low coupling is often thought to be a sign of a well-structured <a href="/facts/Computer_system/SQe1aK05">computer system</a> and a good design, and when combined with high cohesion, supports the general goals of high <a href="/facts/Computer_programming/QmSsFnu0">readability</a> and <a href="/facts/Maintainability/SmyLaINQ">maintainability</a>. </p>
