How are Reviews saved to the Review Repository?

In the DatabaseLoader class, we add Reviews to a Course like so

Course course = new Course("Java Basics", "https://teamtreehouse.com/library/java-basics");
    course.addReview(new Review(3, "Test review"));
    courses.save(course);

In the Course class, we have the addReview method that adds the review to the Courses private field of Reviews

public class Course extends BaseEntity{
 @OneToMany(mappedBy = "course", cascade = CascadeType.ALL)
  private List<Review> reviews;

  public void addReview(Review review){
    review.setCourse(this);
    reviews.add(review);
  }

At what point are the reviews saved to the Review Repository? We never create an instance of the ReviewRepository and call the save method, yet the Reviews are added to the database. Is this because of Cascading or because of the @OneToMany and @ManyToOne annotations?
