Chapter 5 Managing Models
A diagram is a graphical view of a model or a package. In a diagram, you can see the symbols of objects belonging to a model or a package.
You can use diagrams when models and packages become really large and contain numerous objects; in this case, diagrams allow you to split the display and focus on certain portions of the models or packages.
Diagrams can also be used to view subject areas. They allow you to see the symbols of the same objects, displayed with different kinds of information.
All models and packages have at least one diagram, the default diagram that appears when you create a new model or package. They can contain several diagrams.
Requirements Model views
In the Requirements Model, the concept of diagram is replaced by the concept of views. For more information on views, see the Requirements Model User's Guide.
When you decompose a package into packages, diagrams are created at the different decomposition levels. You can use the navigation feature to browse the global hierarchy of packages in the model.
