Connecting your Rails application to a database #

Rails default setup uses sqlite which is a great way to get starting building applications, but at some point we will need to connect to a real database. Whether you need functionality that is specific to a certain database, or you want to simulate your production environment more. Connecting to a database is pretty easy with Rails. The first thing you will need is a database installed on your computer. For my apps I primarily use Postgres and pgAdmin as my GUI.
