I am not aware of any such DBMS. Every DBMS I've ever seen manages
(let us call them) "objects" that are mere software. They are in no
way "real world objects". It is the designer's job to define those
objects reflective of the real world, and the user's job to maintain
the modelled objects such that accurately reflect the real world. Only
then is the DBMS able to provide logical inferences from the
model that can be meanfully applied to the real world (again, by the
user).
