Study Notes
Introduction to Object Oriented Analysis and Design (OOAD)
- OOAD is a software development approach that emphasizes a logical solution based on objects.
Object-Oriented Application
- A collection of discrete objects that interact with each other.
- Objects have properties and behaviors that cause state transitions.
- Interactions occur through message passing, where a sender object sends a request (message) to a receiver object to invoke a method of the receiver object.
Object Structure
- An object consists of:
- Data
- Functions (methods)
- Messages (requests) sent to other objects
OOAD Process
- Analysis: understanding, finding, and describing concepts in the problem domain.
- Design: understanding and defining software solutions/objects that represent the analysis concepts, which will eventually be implemented in code.
- OOAD involves both a notation and a process.
