2. What is UML?
 UML stands for Unified Modeling Language. It is modeling language
used for designing graphics design.
 It is standard language for specifying, visualizing, constructing
and documenting the artifacts of software system.
 UML diagrams are important part of developing object oriented
software and the software development process.

3. Use of UML
 UML is an open standard, Graphical notation for specifying, visualizing,
constructing and documenting software systems.
 Support for UML in many software package like Rational, plugins for IDE like
NetBeans, Eclipse.
 By the diagram view the understanding/communication of product to
customer and developers Increases.
 Support for diverse application areas

4. History of UML

5. Types of UML

6. Use case diagram
6
• overview the usage requirements
• presentations project stakeholders
• "the meat" of the actual requirements
Actor:
An actor is a person, organization, or external system that
plays a role in one or more interactions with your system
Use case:
A use case describes a sequence of actions that provide value
to an actor and is drawn as a horizontal ellipse

7. Example of Use Case detail

8. Class Diagram
8
Class diagrams show the classes of the system, their interrelationships (including
inheritance, aggregation, and association), and the operations and attributes of
the classes.

9. Example of Class Diagram
Name
Attributes
Operations
Relations
• Associations
• Aggregation
•Generalization

10. Activity Diagram
 UML 2 Activity diagrams helps to describe the flow of control of the target
system, such as the exploring complex business rules and operations,
describing the use case also the business process. It is object-oriented
equivalent of flow charts and data-flow diagrams (DFDs).

11. Example of Activity Diagram
Activity Diagram
Branch
Start
End
Action

12. Object Diagram
 Object Diagrams is similar to class diagrams. It is UML structural diagram that
shows the instance of the classifiers in models. It uses notation that is similar
to that used in class diagrams. It shows the static design of system but from
the real prospective.

13. Example of Object Diagram
Object

14. Component Diagram
 Component Diagram represents how components are wired together to form
longer component or software system. The purpose of the component
diagram is to show h relationship between different components.

15. Example of Component Diagram
Component
Connection

16. Sequence Diagram
 Sequence Diagram is also called interaction Diagram which shows the way
that how he process operates with one another. It focus on the message
interchange between a numbers of lifeline. It models the collaboration of the
object based on a time sequence.
The following nodes are used in UML Sequence Diagram:
• Lifeline
• Execution Specification
• Message
• Combined Fragment
• Interaction Use
• State invariant etc…

17. Example of Sequence Diagram
Action
Sequence-Actor
Message

18. Deployment Diagram
 In UML the Deployment Diagram models the physical deployment of artifacts
on nodes. It also helps to model the physical aspect of an Object-Oriented
software system. In this type of UML Diagrams nodes are appear as boxes and
the artifacts allocated to each node appear as rectangles within the boxes.
 For an example: If we want to describe a web site with Deployment Diagram
then the hardware components i.e. “nodes” exists ,what software
components i.e. “artifacts” run on each node and how different pieces are
connected.
 There are two types of Nodes:
 Device Node
 Execution Environment Node
