1. Object Oriented Analysis and Design
Object Oriented Analysis and Modeling

2. Model
System representation of a thing, specially of a system

3. Model A representation of what is going to build
May have number of views
A model is quicker and easier to build
Represent real or imaginary things from any domain.
Use in engineering
Useful for understand of system

4. UML
UML (stands for Unified Modeling Language) is a standard modeling language with graphical representations for specifying, visualizing, constructing, and documenting the artifacts of systems

5. UML Modeling Language Graphical elements Rules Describe
System Functions
System data
System Structure
Doesn't tell how to implement

6. Building blocks of UML
Things
Relationships
Diagrams

7. Building blocks of UML Things: Basic entities in a model
Things can be: Structural, Behavioral, Grouping, and Annotational.
The structural things define the static elements.
The behavioral thing define dynamic features.
Grouping things can be defined as a mechanism to group elements of a UML model together.
Annotational things can be defined as a mechanism to capture remarks, descriptions, and comments of UML model elements.

8. Building blocks of UML Relationships: Associations between elements
Association describes the functionality of an system.

9. Building blocks of UML Diagrams:
Graph of things and their relation ships
Diagram represents a system.

10. Advantages of UML Easy to understand by any one since pictorial
Capable of representing both structure and behavior
Capable in object oriented analysis
Supporting reusability
Independent of specific programming language
Accepted and used by everyone
