Questions tagged [models]

A model is an abstract representation of a real-life object or process. Models are a part of the popular MVC pattern, as well as a more general concept in the sciences for approximating behavior.

A model is one of the three components of Model-View-Controller (MVC) programming pattern that provides knowledge: data and how to work with this data, responding to requests by changing its state.

It can also refer to models in a more general scientific sense, denoting a representation (generally a simplification) of how a real-world process operates.
