Purpose

This tool mentor describes how to represent the design model and related artifacts in Rational Rose. The 'Rational Unified Process' Rose model template, provided with Rose, provides the structure described below.

Overview

The following steps are performed to manage the Artifact: Design Model:

  1. Create the Design Model

  2. Create packages in the Design Model
  3. Create layers in the Design Model
  4. Document the Model organization

1. Create the Design Model To top of page

The Artifact: Design Model can be represented in Rational Rose using a package within the Logical View named "Design Model". The design model represents a level of abstraction close to the source code. For example, classes in the design model typically have a language and model properties assigned, which define the mapping to code.

2. Create packages in the Design Model To top of page

A package is a general-purpose model element that organizes model elements into groups. A system may be thought of as a single, high-level package, with everything else in the system contained in it.

For more information about packages, refer to the Package topic in the Rational Rose online help.

3. Create layers within the Design Model To top of page

A model may contain several layers, which you visualize as packages, one package per layer. Layers may be nested. To distinguish packages as layers you should add the stereotype "layer" to each package. In addition, you should use the Documentation field in the Package Specification to describe the package.

4. Document the Model organization To top of page

Every model needs a class diagram showing the layer and subsystem organization of the model. This should be the Main diagram. Consider renaming the diagram "Model Organization". Drag and drop the packages that represent the layers or subsystems into the diagram.
