I really agree with you Steven Steven Gordon <[EMAIL PROTECTED]> wrote: "MDA will never be as flexible and malleable as textual code"?? Is C++ less flexible and malleable than the sequence of 1s and 0s it represents in machine language?
"and the code has to come first"?? Does the machine language code have to come before the C++ code? Or are you just referring to bootstrapping - the fact that the first MDA tools would have to be implemented in current languages before subsequent generations could be built with MDA tools? There is no theoretical barrier to flexibility and malleablility in MDA. There might be business, political, and marketing barriers. We will never get sufficient agility unless we demand it and then be good customers for the iterative process of building sufficiently agile tools. -----Original Message----- From: Ramon Leon [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 30, 2004 2:34 PM To: [EMAIL PROTECTED] Subject: RE: [XP] XP Survival > -----Original Message----- > From: Israel Antezana [mailto:[EMAIL PROTECTED] > Sent: Tuesday, November 30, 2004 2:22 PM > To: [EMAIL PROTECTED] > Subject: RE: [XP] XP Survival > > > > Ramon Leon wrote: > > >Whether the language is visual or textual, you still need to build a > >model, and the model still needs to evolve via iterations > and feedback, > >XP still applies. > > What do you think about TDD in an MDA context? As I just said, it doesn't matter how or where the code comes from, a domain model is a domain model and you won't get it right the first time, you'll build it iteratively, therefore XP still applies. No magic new tool will suddenly make you a domain expert, and programming is as much about learning where you misconceptions are as it is about writing software. XP will apply regardless of how fancy the tools get, it's just plain good engineering. MDA isn't new, people have been trying to do it for a long time, some people just want graphical programming. The problem remains what it always has been, models tend to force a particular view of how things should work upon the programmer, and as long as that is appropriate for the situation, it'll work, but MDA will never be as flexible and malleable as textual code, after all, the model is simply a view of the code... and the code has to come first. Programming isn't easy, and when you try and make it look easy, you fool people into thinking they can build things they can't, and they abuse the tools and forget what goes on underneath, and suddenly good architecture goes out the window. I don't have much faith in MDA, but to each his own.
