Woof! It was a job to get that file. Tried seven (7) different PDF [Windows] printers, finally had to subscribe to Scribd - a process much more drawn out than it should have to be - before I could download it. I did get through the first 35 pages - all that one of the PDF printers would produce - and I'll get through the rest in the next couple of days, even though my preferred learning method is kinesthetic, not visual. The document is a bit clearer than the others I've seen.
That said, what I'd really like to find is reviews/comparisons/testimonials anent the various flavours of NoSQL by folk who've actually used it. Searches have provided me little of content in that respect. I'm looking for the usual stuff from folk who have had some experience with it: why they chose it, how it worked for them, the upsides & downsides of their application of it. On the face of it, I've seen very little to tempt me to change from MySQL. In fact, most of what I've seen implies that I'll need to learn Python in order to really make use of any of the NoSQL applications available.
Granted, that opinion's based upon a cursory inspection of the few implementations I've seen, and is subject to change. Long and the short of it, though, is that I've seen no compelling reason to change my current methodology, other than just doing something new and different. I like new and different, but where a client is involved, it's difficult to justify experimentation w/o some reasonable expectation of a better outcome.
