define coupling in software engineering
Data coupling- Data coupling is when two modules interact with each other by means of passing data (as parameter). Coincidental cohesion: the parts of a component are not related but Cohesion: Cohesion refers to the strength of relationship between elements within a module. Functions still weakly connected, and again unlikely to be reusable in Type cohesion: modules that support a data abstraction. Tight coupling is a coupling technique in which hardware and software components are highly dependent on each other.
between modules, the more dependent they are in the sense that more info 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.. Coupling is usually contrasted with cohesion. M An interface If … interface difficult to understand. Procedural cohesion: a single control sequence, e.g., a loop or sequence as start up or shut down, are brought together. Coupling is the act of joining two things together. When one module modifies local data values or instructions in another Cohesion of module considered as B
