Loose coupling

System with weakly-associated components / From Wikipedia, the free encyclopedia

Dear Wikiwand AI, let's keep it short by simply answering these key questions:

Can you list the top facts and stats about Loose coupling?

Summarize this article for a 10 years old


In computing and systems design, a loosely coupled system is one

  1. in which components are weakly associated (have breakable relationships) with each other, and thus changes in one component least affect existence or performance of another component.
  2. in which each of its components has, or makes use of, little or no knowledge of the definitions of other separate components. Subareas include the coupling of classes, interfaces, data, and services.[1] Loose coupling is the opposite of tight coupling.
