The illustration below shows some of the model diagram's key elements. The Layered Application model is a container amodel that contains three other models: the Presentation Layer, the Business Layer, and the Data Layer. There are defined dependencies between these included models. Packages are commonly found in models. Dependencies or other relationships, such as import, could be determined between packages.
