Study Notes
Object-Oriented Analysis and Design (OOAD)
- The "software crisis" in the 1960s and 1970s was caused by communication difficulties and the management of complexity.
Why Object-Oriented?
- The Whorfian Hypothesis states that language shapes our perception of reality and influences how we think and communicate.
- Concepts are needed to bring order and structure to our understanding of the world.
- Concept formation is a process of going from chaos to order, and it's an innate human capacity.
Human Growth and Concept Formation
- Infants perceive the world as a "buzzing confusion" and as they grow, they start to form individual concepts (e.g., "blue" and "sky").
- As children get older, their concepts become more complex and nuanced (e.g., "blue sky" only on cloudless days).
- This process of concept formation is essential for understanding and communicating meaning.
Conceptual Modeling
- A concept diagram is a way to represent complex concepts and relationships, and it's essential for understanding and communicating meaning.
- An example of a concept diagram is a first-grade student's diagram of concepts like "water", "salt water", "oceans", and "penguins".
Why Object-Oriented?
- A model is a simplification of our perception of reality, and it's essential for understanding and communicating complex ideas.
- Models are abstractions of reality, and they help us detect commonalities and differences in our perceptions of reality.
What is Object-Orientation?
- An "object" is anything to which a concept applies, and it can be a thing from the problem domain or solution space.
- An object has identity, properties, and behavior, and it's an instance of a collective concept (a class).
Abstraction and Encapsulation
- Abstraction involves focusing on the essential features of an object and omitting unnecessary details.
- Encapsulation is the process of hiding internal details of an object and only exposing its essential features.
What is Object-Orientation?
- A class is a collection of objects that share common properties, attributes, behavior, and semantics.
- Instantiation is the act of creating an instance of a class.
Class and Inheritance
- Specialization is the process of defining one class as a refinement of another.
- Subclass is a class defined in terms of a specialization of a superclass using inheritance.
- Superclass is a class serving as a base for inheritance in a class hierarchy.
