What is Object-Orientation?
A technique for system modeling

OO model consists of several interacting objects

What is a Model?
A model is an abstraction of something

Purpose is to understand the product before
developing it

Examples – Model
Highway maps

Architectural models

Mechanical models

…Example – OO Model
lives-in
Ali House
Objects
Abu Bakar drives
House
Car
Car Tree
Tree
Interactions
Abu Bakar lives in the house
Abu Bakar drives the car

Object-Orientation - Advantages
People think in terms of objects

OO models map to reality

Therefore, OO models are
easy to develop
easy to understand

What is an Object?
An object is

Something tangible (Ali, Car)

Something that can be apprehended intellectually
(Time, Date)

… What is an Object?
An object has

State (attributes)
Well-defined behaviour (operations)
Unique identity

Example – Ali is a Tangible Object
Name
Age
behaviour (operations)
Walks
Eats
Identity
His name

Example – Car is a Tangible Object
- Color
- Model
- Accelerate - Start Car
- Change Gear
Identity
- Its registration number

Example – Time is an Object
Apprehended Intellectually
- Hours - Seconds
- Minutes
- Set Hours - Set Seconds
- Set Minutes
Identity
- Would have a unique ID in the model

Example – Date is an Object
Apprehended Intellectually
- Year - Day
- Month
- Set Year - Set Day
- Set Month
Identity
- Would have a unique ID in the model
