How do you implement a custom repository in Magento?

Answer: To implement a custom repository in Magento, follow these steps:

1. Create the Repository Interface: Define an interface for your repository with necessary methods.

2. Implement the Repository Class: Create a class that implements your interface. Use dependency injection to include any required services and models.

3. Use Service Contracts: Ensure your repository adheres to Magento’s Service Contracts by implementing `getById`, `save`, `delete`, etc.

4. Register the Repository: Create a di.xml file in your module to define your repository in DI (Dependency Injection).

5. Use the Repository: Inject your custom repository into your classes where needed, such as controllers or models to utilize its functionality.

6. Testing: Write test cases to ensure that your repository behaves as expected.

This structure will give you a clean, maintainable, and extensible repository suitable for your custom module.
