Rose top-level model views

Rational Rose® required the use of the following views in every model: use case, logical, component, and deployment. While all Rose models import using this model organization structure, you are not required to keep your models organized in the same way within the new Rational® UML modeling products.

The top-level model views are often referred to as the 4+1 or 3+1 view of UML diagrams. In Rose, each view represents a different way to look at the same system you are modeling, but from different levels of abstraction.

Compared to Rose, you have more freedom to organize your model at a higher level. Upon import, each use case, logical, component, and deployment view will appear in the Model Explorer view, but as top-level packages. The new UML modeling products give you the flexibility to capture architectural views as separate models, or as actual diagrams in the models that they are views of; for example, you can model the use-case view as a diagram in the use-case model file.
