title: Where can I "practice" PL/SQL
body: <p>I will be given a job offer by an IT company, and was asked to "look at" PL/SQL since I didn't have much experience with databases. I have an extensive background in C++ among other programming languages, so I don't think this will pose too much of a challenge. However, I don't have access to any Oracle database at home, so I was wondering if there is a "toy" database and terminal online where I can practice.</p>
