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

Object-Orientation - Advantages People think in terms of objects
OO models map to reality
Therefore, OO models areeasy to developeasy 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 ObjectState (attributes)
NameAge
behaviour (operations)WalksEats
IdentityHis name
Example – Car is a Tangible ObjectState (attributes)
- Color- Model
behaviour (operations)- Accelerate - Start Car- Change Gear
Identity- Its registration number
Example – Time is an Object Apprehended IntellectuallyState (attributes)
- Hours - Seconds- Minutes
behaviour (operations)- Set Hours - Set Seconds- Set Minutes
Identity- Would have a unique ID in the model
Example – Date is an Object Apprehended IntellectuallyState (attributes)
- Year - Day- Month
behaviour (operations)- Set Year - Set Day- Set Month
Identity- Would have a unique ID in the model
