Question: What is a UML Model?
The model captures the important aspects of the thing being modeled from a certain point of view and simpliﬁes or omits the rest. Engineering, architecture, and many other creative ﬁelds use models. A model is expressed in a medium that is convenient for working.
- Models of buildings may be drawings on paper, 3-D ﬁgures made of cardboard, or ﬁnite-element equations in a computer.
- A construction model of a building shows the appearance of the building but can also be used to make engineering and cost calculations.
- A model of a software system is made in a modeling language, such as UML.
The model has both semantics and notation and can take various forms that include both pictures and text. The model is intended to be easier to use for certain purposes than the ﬁnal system.
