Packages are used to organize and handle complexity in large models. A package groups model
elements and diagrams such as use cases, classes, activities, processes, states, etc. and their
associated diagrams, in such a way that it can be referred to as a whole. Packages can then be
depicted in a diagram, referred to as a package diagram.
A package is depicted by a rectangle with a little tab within which the name of the package is
recorded.

Packages may have relationships with other packages to show what the dependencies are between
the packages. Dependency relationships are used to show how packages are dependent on each
other.
