Software Cohesion And Coupling. Increasing in cohesion is good for software. Coupling and Cohesion Module Coupling.
In a content coupling one module can modify the data of another module or control flow is passed from one module to the other module. If the dependency between the modules is based on the fact that they communicate by passing only data then the modules are said to be data coupled. The degree of coupling between two modules depends on their interface complexity which is basically determined by the number of types of parameters that are interchanged while.
Cohesion is the degree to which all of the methods and data structures in a class or module are related to one another and belong together.
In software engineering the coupling is the degree of interdependence between software modules. If two modules interchange huge amounts of datainformation then they are highly interdependent. In software engineering the coupling can be defined as the measurement to which the components of the software depend upon each other. Increasing in cohesion is good for software.
