Connascent Software Components
Connascence is a software design metric introduced by Meilir Page-Jones that quantifies the degree and type of dependency between software components, evaluating their strength (difficulty of change) and locality (proximity in the codebase). It can be categorized as static (analyzable at compile-time) or dynamic (detectable at runtime) and includes forms such as Connascence of Name, Type, and Position, each representing different dependency characteristics and levels of fragility. Coupling vs Connascence Coupling describes the degree and nature of dependency between software components, focusing on what they share (e.g., data, control flow, technology) and how tightly they are bound. It evaluates two key dimensions: strength, which measures how difficult it is to change the dependency, and scope (or visibility), which indicates how widely the dependency is exposed across modules or boundaries. Traditional coupling types typically include content coupling, common coupling, contro ...
