I made a few changes to the Rational Software Architect tutorial part 1 post below based on some very valuable feedback from Charles Rivet on the features in the different tools. I redid the diagram from a Venn diagram into a software stack diagram. This is because there are several important features common to all of the tools and this was difficult to show in the Venn diagram (not the overlapping circles, but rather putting readable text in overlapping circles).
It's going to be my policy on these RSA Tutorials that I will correct any factual errors at any point in time. Normally I don't change blogs after the fact, but these aren't simply journal entries or opinions; they're meant to educate people on the tool, so I want them to be as correct as possible.
To be clear, I will only change factual errors; if I state an opinion or make a judgement that I later regret, I will let this stand.
