Cohesion shows the module's relative functional strength. Coupling - A measure of how much a module (package, class, method) relies on other modules. Coupling Coupling is measure of the independence of components. Try to adhere to the "high cohesion and low coupling" guideline on all levels of your code base. Coupling: In software engineering, the coupling can be defined as the measurement to which the components of the software depend upon each other. Coupling measures interaction between modules whereas Cohesion focuses on interaction within a module. -- S. Bloch] "Coupling" describes the relationships between modules, and "cohesion" describes the relationships within them. High cohesion increases the probability that a component can be reused in more places, by limiting its capabilities to small well-defined tasks. Cohesion 2. Coupling is usually contrasted with cohesion. That from of attraction by which the particles of a body are united throughout the mass, whether like or unlike; - distinguished from adhesion, which unites bodies by their adjacent surfaces. The more cohesive a module is, relative to other modules in the software, the more independently it can operate. Cohesion Cohesion is the indication of the relationship within module. The coupling metrics presented in this paper exploring the difference between inheritance and interface programming. Cohesion is the indication of the relationship within the module. It is desirable to reduce coupling, or reduce the amount that a given module relies on the other modules of a system. Highly cohesive classes are much easier to maintain .
