title: How to connect to SQL developer using my own database
body: <p>I'm currently using SQL Developer 4.5.1.21 and want to take some time to learn language, run queries etc etc. I'm using a database that Oracle provides called "HR Schema" that is free for download. Now I know that I need to create a "connection" in order run queries onto this database. I begin running into trouble when I want to create my own connection. Can anybody walk me through the steps of creating a new connection? What I do is click the "+" button and click "new connection".</p>
