Does anybody see that that the movieDetails collection is gone?
You are connected to the Class cluster. In the class version, it is simply named “movies”. In our own cluster, the name is “movieDetails”
Correct! Both datasets have different contents, different fields and different schema. You have to pay attention to each assignment and exercise, because the MongoU people will tell you which database you need: either the shared “movies” db, or your personal “movieDetails” db.
