Okay, here many truth, but.

But I see that a lots of NEW software is developed with RDBMS
(even not ORBMS)...so not only this is a reason.

Well, this can be of course inertness of developers...
They have many years learn relational model...

And this is why we have choose for Valentina soft,
evolution way like C++ did in the past to eat C.

Everything that work in RDBMS work in Valentina 2.x,
Plus it have new features, which you can use when learn them.
