Honestly, if you're going to make a serious study of the subject, I'd suggest an O'Reilly Safari subscription. For $15 a month, you get access to 10 books at a time. For $40 a month, you get access to their entire library. I'm not a shill for the service, I just really like the service. It's well worth the cash. Online tutorials are good for a quick, down and dirty overview of a topic. But, if you're going to learn something a bit more in depth, I'd think that you're better off looking at a book. It's pricey, but it's worth it for me. I figure I'd spend $40 a month on tech books anyway. I'd might as well pay them and get the whole library as well as the Lynda.com video all at the same time. Also, if you're really serious about it, I might consider finding a web database development class or certificate program somewhere. It might be slower going than you want, but you'll have a more complete understanding of the subjects once you were done.
