System model

A system model (which is always an abstract system) is used to describe and represent a system which may be real or abstract. A real system, e. g., houses, trees, airplanes, etc., exists in the real world. An abstract system, e. g., symbols, languages, diagrams, etc., exists in the abstract world.

A system (real or abstract) comprises multiple views such as analysis view, design view, implementation view, deployment view, structure view, behavior view, input data view, and output data view, etc. A system model is required to represent all these multiple views.
