Tool Mentor: Documenting the Deployment Model Using Rational Rose

Purpose

This tool mentor describes how to represent the Deployment Model and related artifacts in Rational Rose.

Related Rational Unified Process information: Activity: Describe Distribution.

Overview

The Rose Deployment View enables you to document the processors, the processes allocated to those processors, devices, and connections that comprise your Deployment Model. Processor Specifications, Device Specifications, and Connection Specifications enable you to display and modify their respective properties. You can change properties or relationships by editing the specification or modifying the icon on the diagram.

The following is a summary of the steps you perform to manage the Deployment View:

1. Create a node in the Deployment View

2. Map processes to nodes
3. Create a Device in the Deployment View
4. Create Connections between devices and nodes
5. Annotate the Deployment View

For more information about the Deployment View, see the Deployment Diagrams (Overview) topic in the Rose online help.

1. Create a node in the Deployment View

A node in the Deployment View can be either a processor or a device. You can further define a processor by identifying its processes and specifying the type of process scheduling it uses.

2. Map processes to nodes

Processes represent single threads of control. Examples include the main program from a component diagram or the name of an active object from a collaboration diagram. To document the processes and threads that execute on a particular node, you add the process or thread to the Processor using the Processor Specification.

3. Create a device in the Deployment View

A device is a hardware component with no computing power. Each device must have a name. Device names can be generic, such as "modem" or "terminal."

4. Create connections between devices and nodes

A connection represents some type of hardware coupling between two nodes, either a processor or a device. The hardware coupling can be direct, such as an RS232 cable, or indirect, such as satellite-to-ground communication. Connections are usually bi-directional.

5. Annotate the Deployment View

You can describe elements in the Deployment View by creating a note and linking it to a specific node or connection. You can also use a note to link a diagram in another view to the Deployment View. For example, you can link a note to a Component Diagram. Once a diagram is linked, you can double-click on the note and the linked diagram is immediately displayed. A linked diagram is indicated by underlined text in the note.
