MDE equation: models + transformations = software
I think it’s time to revisit Niklaus Wirth famous equation:
Algorithms + Data Structures = Programs
from a MDE (didactic) perspective. I propose the following MDE equation:
Models + Transformations = Software
Of course, it’s a simplification of the reality (well, in the same way Wirth’s one was, in both cases we omit, for instance, the grammar/metamodels involved) but gives a very simple way to explain what MDE is to novices (as we pretend to do in our future book).
In fact, we can even go one step further (once novices have understood the basics!). Since transformations can be represented themselves as models, we could just write:
Models + (Transformation) Models = Software
which could be “conceptually” simplified as:
Models = Software
that cleary shows that MDE practitioners have the absolute truth to software development
