What does posts stand for
It's not a Mongo-specific thing, it's just asking what it means when it's placed after the
db. in a command in the Mongo shell.
For a hint, if this were a relational database, it would be
db.table, but Mongo calls 'tables' something else. In this case,
posts is the name of that particular instance of a structure in the Mongo database.
