This project presents my research on Design Patterns in the context of Object-Oriented Analysis and Design (OOAD). Design patterns are general, reusable solutions to common problems that occur in object-oriented software design. They provide best practices that help developers create flexible, maintainable, and scalable systems.
Through this research, I explored how design patterns improve code structure, promote reusability, and support important OOP principles such as encapsulation, abstraction, inheritance, and polymorphism. I also studied how patterns are categorized into creational, structural, and behavioral types, and how each category solves different kinds of design problems.
The concept of design patterns was popularized by the book Design Patterns: Elements of Reusable Object-Oriented Software, written by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, also known as the "Gang of Four."
I did research on this topic because I want to improve my understanding of Object-Oriented Programming (OOP) and learn how to design better software systems using proven and structured approaches.
