I read over the white papers they had at the site, and this looks like a case tool. Back in the early 80's when everyone was talking about language and computer generations, case tools where one of the proposed 5th gen languages.
The idea of the case tool was to create a language for specify a program at a high level, incorporating buisness logic and so on. The case tool would then build the code needed for the application, usually outputting source code that the developers then could touch up to add features the case tool didn't cover.
Case tools where all the rage for a while in some industries, mostly heavily regulated ones, where every company needs similar applications and has similar internal process.
Nobody could ever break out into the general buisness market though, and the idea eventually died off.
