You can DO NOT build BaseObject classes.
And work just with 

    Vdatabase -> Vcursor -> Vfield

Conception.

Do not touch BaseObject's RECORD API for now.

If we will lucky in V4RB 2.0 I will add some more functionality to
BaseObject API. In dream, BaseObject API must allow us work with tables,
Records and fields WITHOUT SQL !!!  Using Navigational model

I will not explain now what is this...

Practically NO.

Valentina's API yes of course.

James, problem with REAL DB API as far as I see,
    1) it is VERY LIMITED by field types for example.
    2) it do NOT allow add more types.

So in REAL DB API you cannot use for example such cool feature of Valentina
as ObjectPtr and other new features that we will get in 2.0.

As for me, REA DB API is for VERY small projects,
Or for really "paranoid people" that want to have in project a lots of
supported DB sources.
