Design Patterns

What are Design Patterns?

In software development, design patterns are reusable solutions to common problems. They provide a way to create flexible and maintainable software by promoting best practices in design and architecture.

Why Design Patterns?

Design patterns offer several benefits:

  • Reusability: Solve common problems in a reusable way.
  • Scalability: Provide a structured approach to software design.
  • Maintainability: Capture best practices for future reference.
  • Collaboration: Establish a common vocabulary for discussing solutions.

Included Design Patterns

Briefly mention any design patterns that are prominently used in your project. For example:

  • Singleton Pattern: Used to ensure a class has only one instance.
  • Prototype Pattern: Used for object creation by cloning an existing object.
  • Builder Pattern: Facilitates the construction of complex objects step by step. Useful when you need to create an object with many optional components.
  • Decorator Pattern: Allows behavior to be added to an individual object, either statically or dynamically, without affecting the behavior of other objects from the same class.
  • Observer Pattern: Defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically.
  • Facade Pattern: Simplifies the interaction with a complex subsystem by providing a unified interface. It acts as a higher-level interface that makes the subsystem easier to use for clients.
