Object Oriented Analysis

by John F. Bergin

There are 4 major components of Object Oriented Analysis:

Abstraction

Abstraction is used to simplify a situation by representing different objects using attributes common to both. Example: “Dogs” and “Cats” can be

abstracted as “Pets”. In C#, abstraction is achieved using “Derived Classes”

Encapsulation

Encapsulation, or “Information Hiding”, conceals information about an object from other objects that interact with it. In C#, encapsulation is achieved

through “Class Definitions”, or the class “Interface”. In C#, encapsulated functions can be either “public”, “private”, or “protected”.

Inheritance

Inheritance is used to create new classes of objects from existing classes. In C#, inheritance is achieved using “Sub-Classes”.

Polymorphism

Polymorphism allow a single method to be used with different types of objects. In C#, polymorphism is achieved through “Class Definitions”.

Polymorphism can be “Overriding”, “Overloaded”, or “Parametric”.
