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 planning view, 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 describe and represent all these multiple views.
