I’m preparing an overview of xUML, MDA and UML, how they fit together and most of all about advantages and disadvantages of using this methodology. I googled a little bit and although in theory those look pretty promising, I really couldn’t find much success stories, nor tools supporting xUML (I found only 2: iUML and Cassandra). Generating complete code generated from model seems tempting, so why noone is using it? Is it lack of tools? Or maybe it’s all too vague, too imprecise, and people are afraid, that, after all they will have to dive into this generated model and tune it up manually, so why bother at all? What do you think?
