Vocabulary

Collection

Collections are analogous to tables (but does not require its documents to have the same schema).

Database

Databases hold groups of logically related collections.
MongoDB creates new databases implicitly upon their first use.

Document id

Documents stored in a collection must have a unique _id field that acts as a primary key.
