It‘s totally crazy that in 2012 there are so few good choices for modeling tools. I got encouraged for a minute today when I found a thread on Stack Overflow that included a bunch of products and I found out about SparxSystems‘ System Architect . Got all the way to downloading the trial version when I saw that it was an exe. Yes, folks, Windows only.. in 2012. Unbelievable. Hilarious that these guys are selling tools for doing MDA. Guys, where is your PIM? Oh, yeah, you don‘t have one (clearly). Your codebase is already a PSM (platform-specific model).
