Process

1. Gemfile is used to store all the libraries and dependencies you'll need to launch and deploy your app.
2. Procfile is the process file you used to kickstart your app.
3. Foreman is the toolkit you use to automatically start-up your server
4. SQLite is what you'll use for a local SQl database
5. Postgresql is the SQL database you'll use for production
6. config.ru is the configuration file that connect Procfile to your initial app.rb file.

Adding a new property to the Database

Add the property within the class

 property :likes, Integer, :default => 0

Use IRB to migrate the database

 bash$ irb

Use DataMapper to update the tables

 DataMapper.auto_upgrade!

Test out your work

 bash$ irb

 require './app' 

 bash$ song = Song.first

 bash$ song.likes
