What is Collections in MongoDB:

MongoDB stores data records as documents (specifically BSON documents) which are gathered together in collections.

A database stores one or more collections of documents.

You can manage databases and collections on the Atlas cluster from the Atlas UI, mongosh, or MongoDB Compass.

Show or List Collections using mongosh

You can show or list collection using the show collections or db.getCollectionNames() method.
