I have language L1 (entity model) and language L2 (entity model manipulation). I want to be able to generate new model written in L1 from old model written in L1 and model written in L2. Is it possible to generate model in L1 (not text) using MPS generator?
Also, more general question (problem): does anyone have an approach related to management and maintenance of persistent data scheme using only MPS? Is it even possible? Or should I just let an RDBMS admin to design a scheme and MPS application end user just to translate that scheme into MPS model every time there are any changes?
