What is repository pattern

Question

Accepted Answer

Repository pattern is a design pattern that separates data access logic from business logic.

It provides a way to access data without exposing the underlying database or data storage technology.
It helps in achieving separation of concerns and makes the code more modular and testable.
It involves creating a repository interface that defines the operations that can be performed on the data and a concrete implementation of the repository that interacts with the data storage technology.
Example: A repository interface for a user entity can have methods like addUser, getUserById, updateUser, deleteUser, etc.
Example: A concrete implementation of the repository can use SQL queries to interact with a relational database or use HTTP requests to interact with a REST API.
