Object Oriented Analysis and Design

Fundamental concepts in OOAD

UML is a powerful tool to represent the concepts in OOAD

• Objects: Objects represent an entity and the basic building block.
• Class: Class is the blue print of an object.
•  Abstraction: Abstraction represents the behavior of an real world entity.
•  Encapsulation: Encapsulation is the mechanism of binding the data together and hiding them from outside world.
•  Inheritance: Inheritance is the mechanism of making new classes from existing one.
•  Polymorphism: It defines the mechanism to exists in different forms.

UML and OOAD 

 UML uses the following design concepts and transforms the design into visual artifacts

• Identifying the objects of a system.
• Identify their relationships.
• Make a design which can be converted to executables using OO languages

 UML can also be used to model non software systems
