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:
-
Create
a node in the Deployment View
- Map
processes to nodes
- Create
a Device in the Deployment View
- Create
Connections between devices and nodes
- 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.
