title: nodejs database migration module
body: <p>I am looking for a good module for migration in node.js application. I am using sequelize as ORM. I have found a couple of solutions such as migration in sequelize itself but I can't find enough examples for adding column(changing schema) or adding enteries into table.</p>
  
  <p>Could somebody give a good module with some good complete examples as well for both altering schema as well as adding existing enteries?</p>
  
  <p>My application is hosted on heroku so could you please also highlight how to use it on heroku?</p>
  
  <p>Thanks</p>
