        The approaches about to specify, create and drop database are likely Oracle DBMS since it has its own built-in methods and tables, has to specify database before performing actions. 

 Specify database 

   According to previous example the collection(a webpage) may have many documents(sets of comment) but it's an example document and its schema here:

This is a document and its schema below

mongod.exe, mongo.exe, server and client respectively

 Create database 

This example added only key 'by' from schema. Actually, it would be Rahul.

 Drop database 

Specify database then drop it.

 Create collection 

A collection will be automatically created once a document is inserted.

 Drop collection  

Be careful to check instance before performing actions!
