This brings us back to the original questions :-)
: Why should I query? It is for untyped tables. If I have an object at hand

: have another object, a container that refers to my object. That container

Relations. Records In DB system, as well as records in Ada have components
which can be updated. Relations between 2 or more objects may thus depend
on time. However, an object's type cannot reflect this, because types
are static. You could associate one different type with each possible
combination of component values in your program...
