Coupling in software

Any change performed on the global information field return and prompts every one of the modules that have gotten to the data through it. It can make some transmission errors and unidentified issues when the changes are made to global information.

And this makes issues while reusing the modules and limits the capacity to deal with information access of various modules on a similar information source. We can control this coupling by reducing the use of common global data or by separation. Another way to achieve this is by designing patterns for different modules and making them suitable for attaining an acceptable design. Skip to content. Change Language. Related Articles.

Data Coupling occurs when two software system modules have only one type of interaction between them; this can be as simple as data. The rest of the components are not shared resources such as functionality or other operating systems components.

The controlled Coupling is a functional flow where the two software modules network by providing each other access to their respective functions. The impact of this Coupling on software applications can either be positive or negative, as it can be defined based on the control being shared by the said module. Stamp coupling is a way for two modules to work more efficiently by sharing data that has been organized and placed beforehand.

The process of external Coupling is when modules are interrelated with common factors that come from outside them. Types of Coupling In software engineering , Coupling between modules can be identified by looking at the number and type of resources shared with other modules.
