What are repositories in Magento, and how do they work?

Answer: In Magento, repositories are interfaces that provide a standard way to perform CRUD (Create, Read, Update, Delete) operations on entities like products, customers, and categories. They serve as an abstraction layer between the business logic and the database, allowing developers to interact with data without directly handling database queries.

Repositories work by defining methods to manipulate entities, which are usually implemented by a corresponding model class. This structure promotes cleaner code, adheres to the Single Responsibility Principle, and enhances testability by enabling easy mocking of data access layers in unit tests.
