An Introduction to the GoF Design Patterns: Creational, Structural, and Behavioral
This article introduces the seminal GoF design pattern book, explaining its three main categories—creational, structural, and behavioral patterns—along with examples and links to further readings, aiming to build a comprehensive understanding of software design fundamentals.
The book "Design Patterns: Elements of Reusable Object‑Oriented Software" is a milestone in software engineering, authored by the "Gang of Four" (Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides).
It classifies design patterns into three broad categories: Creational patterns, which focus on object creation mechanisms; Structural patterns, which optimize relationships among classes, objects, and interfaces; and Behavioral patterns, which improve interactions and algorithm execution between classes.
Each category encompasses several specific patterns, illustrated in the accompanying diagram, and the article briefly mentions common examples such as MVC and MVVM for web and desktop development.
The author promises future articles that will delve into each of the remaining twenty‑plus patterns, providing detailed explanations and practical scenarios.
Additional resources are linked for readers to explore Singleton, Strategy, and Observer patterns in depth.
