Structural Design Patterns: A Comprehensive Guide for Developers
Covering Adapter, Bridge, Composite, Decorator, Facade, Flyweight, and Proxy, which can help organize objects to create complex structures.
In our previous article, we covered creational design patterns and explained how they can enhance the structure and flexibility of software systems. In this article, we take a closer look at design patterns, specifically focusing on structural design patterns. These patterns offer sophisticated solutions for organizing and combining classes and objects to form more intricate structures. We will examine structural design patterns, provide practical use cases, and include code examples in Python.

Structural Design Patterns
Structural design patterns, as explained in “Design Patterns: Elements of Reusable Object-Oriented Software” by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, focus on how objects and classes are composed to create flexible and robust software systems. These patterns highlight the relationships and interactions between different components, providing a framework for creating complex structures that are decoupled and maintainable.
There are seven widely recognized structural design patterns:
- Adapter Pattern
- Bridge Pattern
- Composite Pattern
- Decorator Pattern
- Facade Pattern
- Flyweight Pattern
- Proxy Pattern
Next, we will examine each pattern in detail, including their use cases and code examples.
Adapter (Wrapper) Pattern
The Adapter pattern facilitates the collaboration of objects with different interfaces by acting as a bridge between them. This pattern is useful when integrating new components with existing code or when working with third-party libraries with…
