UML Component and Deployment Diagrams - Brief Overview

1. COMPONENT AND
DEPLOYMENT
DIAGRAM
Presented by Rajiv Kumar V, 13M510, NITH.

2. INTRODUCTION
• UML diagram classification:
• Static
• Use case diagram, Class diagram
• Dynamic
• State diagram, Activity diagram, Sequence diagram, Collaboration
diagram
• Implementation
• Component diagram, Deployment diagram
• Implementation diagrams describe the different elements
required for implementing a system

3. COMPONENT DIAGRAM
• Models the physical implementation of the software (file
resources)
• Models the high-level software components, and their interfaces
• Dependencies are designed such that they can be treated as
independently as possible
• Components to use with Component Diagram are:
• Components required to run the system(library file, etc.)
• Source code file, and data file
• Executable file (.exe)

4. COMPONENT DIAGRAM
(contd…)
• Component is an Autonomous unit
• Modular
• Encapsulated
• Hidden internals and inaccessible
• One or more interfaces
• Well defined interface lets to access the component’s
operations
• Component and subsystems can be flexibly reused and
replaced

5. Elements of Component
Diagram
• Component Stereotype
• <<executable>>: executable file (.exe)
• <<library>>: references resources (.dll)
• <<file>>: text file, source code file, etc.
• <<table>>: database file, table file, etc.
• <<document>>: document file, web page file, etc.

6. Elements of Component
Component Interface
Component dependencies

7. Elements(contd…)
• Interface may also be shown
using a rectangle symbol with a
keyword <<interface>>
preceding the name
• Services that the component
expects from its environment is
modeled using a socket
• multiple components that
require or provide a particular
interface

8. Component Diagram
(An example)

9. Deployment Diagram
• Describes the physical resources of the system (hardware).
• Software runs on nodes
• Nodes can be PC Client, Storage device, Server. etc.
• Shows physical arrangement of run-time computational
resources such as computer and its interconnections.

10. Elements of Deployment

• Node

11. Elements of Deployment
diagram
Association
Component and nodes

(An Example)

13. CONCLUSION
• Components
• Physical and replaceable part of the system that
conforms to and provides the realization of a set of
interfaces
e.g.:
• COM+ components, Java Beans, …
• source code files
• Documents
• Nodes
• Describes the physical resources and the components it
hold
