Object oriented analysis and design

1. Course Contents
Course code: COMP 410
Curse Name: Object Oriented
Analysis & Design
(OOAD)

2. Objective
•Object Oriented Analysis and Design Using UML
present the concepts and techniques necessary
to effectively use system requirements to drive
the development of a robust design model.
•In this intensive, students can learn to apply the
Unified Modeling Language (UML) to
fundamental object-oriented analysis and
design concepts including architecture, objects,
classes, components, stereotypes,
relationships, and all supporting diagrams.

3. •The UML is used throughout the project lifecycle
to capture and communicate analysis and design
decisions.
•Students will understand OOAD Concepts, learn
to represent it with UML and document it using
UML modeling tool. T
•he class will be concept & Case study driven and
wherever necessary tool will be used.

12. What Is an Object?
•Definition: An object is a software bundle of
variables and related methods.
•As the name object-oriented implies, objects are
key to understanding object-oriented technology.
•You can look around you now and see many
examples of real-world objects: your dog, your
desk, your television set, your bicycle.
•Software objects are modeled after real-world
objects in that they, too, have state and behavior.
•A software object maintains its state in variables
and implements its behavior with methods.

13. •The following illustration is a common visual
representation of a software object:

14. •These real-world objects share two
characteristics: they all have state and they all
have behavior.
•For example, dogs have state (name, color,
breed, hungry) and dogs have behavior (barking,
fetching, and slobbering on your newly cleaned
slacks).
•Bicycles have state (current gear, current pedal
cadence, two wheels, number of gears) and
behavior (braking, accelerating, slowing down,
changing gears).

Time Boxing
•In time boxing, a development cycle is fixed in
length.
•The development team should choose the
work to accomplish within the time frame.
