What Is the Difference Between Diagrams and Models?

Although they might appear to be similar at first glance, a diagram and a model are different from each other. A model is an abstraction that contains all the elements needed to describe the intention of the thing being modeled. This can include all aspects concerning the business, systems, relationships, and more. A diagram is a specific view into what you are trying to understand in a specific context. Diagrams are just one way of looking at all or some part of that model. You can have a specific modeling element exist only once within a model, but the same element can appear on one or more diagrams.
