Chapter 6 Managing Models

Diagrams

A diagram is a graphical view of a model or a package. All models and packages have at least one diagram.

Requirements Model views
In the Requirements Model, there are no diagrams, but rather views. For more information, see the Requirements Model User's Guide .

You can add additional diagrams to a model or package to split the display and focus on certain portions of the system. You can also use multiple diagrams to focus on different subject areas. They allow you to see the symbols of the same objects, displayed with different kinds of information.

For example, in a Publishing model, different diagrams could define the different activities involved in this industry: the printing diagram, the sales diagram, the accounting diagram, the book selection committee diagram.
