title: Creating Database in MongoDB and Inserting data from file
body: <p>I just configured Mongo Db on my system.
  What is the difference between <code>collection and Database</code> in Mongo DB,
  I did db.help() to see different functions.
  But I couldn't find any function to add create db,create table or column etc
  I have a csv file that i want to load in Mongo DB.
  Please help
  Thanks</p>
