Getting started (and "playing around") with PL/SQL (and SQL (and Oracle Database))

Got this email Monday from a fellow new to PL/SQL and Oracle:
I have been in I.T. for a couple of years but always had this feeling that I could do better. I lost that hunger when the company I had worked for 10 years plucked me from the warehouse as a kind of internal promotion program. I guess you could say I slowly settled into a rut. I discovered your site recently and I am in the process of reviewing your tutorial videos (I have also started to read newer technical books). I am sure you have been told before but your tutorial videos are great! My problem is that I think the lessons would "stick" with me more if I had the chance to work with them and "play" around.I have very low self esteem (which I am also working on) so please don't laugh but is there a place that I can download a condensed or tutorial version of Oracle 11g? First, I am always excited to hear from people who are just getting into Oracle Database, SQL and PL/SQL. Our part of the technology…
