In your application course, information is stored in a Course table. Some courses are online and additional information about online courses is stored in an OnlineCourse table. You generate an ED Model from the database. In the resulting model the Course and OnlineCourse have a 1 to 0..1 relationship. You need to modify the model so that the OnlineCourse entity includes all the properties of the Course entity and can be used as a Course entity.

What should you do?
