How to access database on Heroku from Android through RESTful APIs?

I'm trying to learn how to make calls to RESTful Web Services from Android. I wanted to test my app against some free database available online and that's when I came to know about Heroku.

I want to develop a Java web app on Heroku that will implement my RESTful web services and fetch data from Heroku database based on the requests received. But I have no clue where to begin.

Where should I begin and how should I connect a Web app deployed on Heroku to a database on Heroku itself? Where do I begin designing the DB itself?

I'm sorry if this question is repetitive.

Thanks for your time!
