M121 collections

In same tests we have to calculate value (es $unwind lab), but where can i find the collections? and the fields? without this i’m not able to answer!!

Hi @Annalisa_33862,

You have to connect to the class Atlas cluster using the following connection string:

mongo “mongodb://cluster0-shard-00-00-jxeqq.mongodb.net:27017,cluster0-shard-00-01-jxeqq.mongodb.net:27017,cluster0-shard-00-02-jxeqq.mongodb.net:27017/aggregations?replicaSet=Cluster0-shard-0” --authenticationDatabase admin --ssl -u m121 -p aggregations --norc

For the lab: $unwind, you need to use aggregations.movies collection.

Please let me know, if you have any questions.
