Just want to use those collections to do more practices.
Please name the collections you are looking for
I think they all must be under aggregations DB
You might be using the data loaded from the Atlas Cluster’s Load Sample Data option. But you should use the cluster that is mentioned in the initial lectures. In case you missed that please feel free to refer to the first question of this FAQ post for this Course to learn more.
In case you have any doubts, please feel free to reach out to us.
Thanks and Regards.
