Session 9
Component and Deployment
Review




State Diagrams represent the software entities in terms
of their states
Sequence diagram give the visual description of the
sequence of the events that happen within the software
entities being developed
Collaboration Diagrams illustrate the communication
between objects
Activity Diagrams present the activities within the
software entities. This presents a pictorial view of the
flow of events that happens within the system being
developed

Component Diagram



Structural Diagram
Component is a physical and
replaceable part of system
and models physical things
Used to describe the
dependencies between
various software
components

Deployment Diagram

Visualizes the distribution of components across the enterprise
OOAD with UML / Session 9 / 7 of 17
Nodes

Run-time physical object that represents a
computational resource, generally having at least a
memory and often processing capability as well

What is deployment
diagram?



Allow the capturing of the topology of the
system nodes, including the assignment of
run-time elements to nodes
Allows to visually see potential bottlenecks
Formed by Nodes, connections (Shown with
stereo types) and components

Summing up UML
OOAD with UML / Session 9 / 16 of 17
Summary
 Component and Deployment diagrams are Structural Diagrams in
UML
 Component diagrams show the physical placement of the
components in the system
 Deployment diagrams show the interconnection of the hardware
and software components
 Rational Rose, Visual UML and Microsoft Visio are major tools to
create deployment diagrams. Rational Rose is comparatively used
more. Rational Rose is an complete Software Engineering tool.
