Welcome to the final unit of our smart home system project! In this last segment, you'll tackle a series of real-world problems using various design patterns that you've learned throughout the course.

You'll identify the most appropriate design patterns for various problem scenarios and implement them effectively.

You'll encounter situations where you need to choose between patterns such as:

Creational Patterns:

• Singleton: Managing a unique instance.
• Builder: Constructing complex objects.
• Abstract Factory: Creating families of related objects.
• Factory Method: Defining an interface for creating objects.

Structural Patterns:

• Composite: Handling hierarchical data structures.
• Adapter: Allowing incompatible interfaces to work together.
• Decorator: Adding responsibilities to objects dynamically.

Behavioral Patterns:

• Strategy: Selecting algorithms at runtime.
• Observer: Implementing a subscription model to notify changes.
• Command: Encapsulating requests as objects.

By the end of this unit, you'll gain practical experience in not only recognizing design patterns but also effectively applying them to solve complex, real-world problems.

Let’s proceed to the practice section and start applying these design patterns to build our smart home solutions!
