When to Choose Structural Design Patterns?
According to this Design Patterns Cheat Sheet, choose structural design patterns when you need to compose objects and classes into larger structures while keeping them flexible and efficient. These patterns are useful for clarifying relationships between classes, managing object hierarchies, and altering interfaces without affecting clients.
- Structural patterns promote code reuse, simplify system design, and enhance scalability.
- They’re beneficial when dealing with complex systems, integration of new components, or refactoring existing codebases.
We must choose Structural Design Patterns when the Problem is related to Object Assembly.
- Adapter: Acts as a bridge between two incompatible interfaces
- Bridge: Separates the abstraction from the implementation.
- Composite: Handles single and composite objects equally.
- Decorator: Adds behaviors to objects dynamically.
- Facade: Helps in Simplifying the complex system interfaces.
- Flyweight: Shares common parts of state between multiple objects to reduce memory.
- Proxy: Controls the access to an object.
Design Patterns Cheat Sheet – When to Use Which Design Pattern?
In system design, selecting the right design pattern is related to choosing the right tool for the job. It’s essential for crafting scalable, maintainable, and efficient systems. Yet, among a lot of options, the decision can be difficult. This Design Patterns Cheat Sheet serves as a guide, helping you on the path toward optimal design pattern selection. Simplifying complex concepts into easy insights empowers engineers to navigate design patterns confidently.
