Have you worked with Spring Data for database interaction?

Yes, Spring Data significantly simplifies working with databases in Java applications. It provides an abstraction over various data stores and allows creating repositories with minimal code. For example, you can define a repository interface extending JpaRepository, and get ready-to-use methods for CRUD operations without implementing them:

public interface UserRepository extends JpaRepository<User, Long> {
    List<User> findByLastName(String lastName);
}

Spring Data automatically implements this interface, which speeds up development and reduces the likelihood of errors.
