Structural Patterns in Software Design

Software design patterns are reusable solutions to common problems in software design. They are essential for creating scalable, maintainable, and efficient software systems. This tutorial will introduce you to some of the most important structural patterns used in software development.

Overview of Structural Patterns

Structural patterns focus on classifying objects and classes to form larger structures while keeping them flexible and efficient. These patterns help in creating relationships between different classes and objects, making the system more modular and easier to manage.

Key Structural Patterns

1. Adapter Pattern

   • The Adapter Pattern allows two incompatible interfaces to work together. It acts as a bridge between the two interfaces.

2. Bridge Pattern

   • The Bridge Pattern separates an abstraction from its implementation so that the two can vary independently.

3. Composite Pattern

   • The Composite Pattern allows you to compose objects into tree structures to represent part-whole hierarchies. It lets clients treat individual objects and compositions of objects uniformly.

4. Decorator Pattern

   • The Decorator Pattern dynamically adds new functionality to an object by wrapping it in a decorator class. It allows you to add new features to an object without modifying its structure.

5. Facade Pattern

   • The Facade Pattern provides a unified interface to a set of interfaces in a subsystem. It controls access to the subsystem and hides its complexity from the client.

6. Flyweight Pattern

   • The Flyweight Pattern minimizes memory usage by sharing as much data as possible with similar objects. It is useful when a program deals with a large number of objects with the same properties.

7. Proxy Pattern

   • The Proxy Pattern provides a placeholder for another object to control access to it. It is used to create a controlled access to a resource that is expensive or difficult to access directly.
