This document provides a comprehensive overview of design patterns in software engineering, focusing on their classification, purpose, and implementation. It covers three main categories of design patterns: creational, structural, and behavioural, along with decoupling patterns. Creational patterns such as Singleton, Factory, Abstract Factory, Builder, and Prototype are discussed in detail, highlighting how they provide efficient and flexible ways to create objects. Structural patterns includ...
