Introduction

The Repository pattern is a software design pattern that separates the data access logic from the business logic of an application. It provides a way to encapsulate data access operations, such as retrieving, adding, updating, and deleting entities, in a separate repository class.

The Singleton pattern ensures that there is only one instance of a class in the application. This can be useful when you want to share the same instance of a class across multiple parts of your application.

This repository includes the following classes:

• Car: Represents a car entity with properties such as Id, Name, Brand, and Year.
• IRepository<T>: An interface that defines the basic operations for a repository, such as GetById, Add, Update, and Delete.
• CarRepository: Implements the IRepository<Car> interface and provides data persistence for the Car entities using a List.
• CarService: Utilizes the CarRepository to perform operations on the car entities, such as retrieving, adding, updating, and deleting cars.

Features

• Uses the Singleton pattern to ensure a single instance of the repository and service classes.
• Provides basic CRUD (Create, Read, Update, Delete) operations for managing car entities.
