Povray script is a specialized programming language that cannot do everything
languages like C and C++ can do. Also, it's interpreted and thus slow. For a
computing-intensive task other than raytracing, it is certainly better to have
an external programme manage it, and then output the result to Povray. A Pov
script could then manage more graphic-related issues.
In the case of tree generation, your programme could output the positions of
the nodes, and Povray could pick up the nodes and build the tree. Or the
programme could output directly the tree geometry as a mesh.

Povray has no database connectivity, but you can make scripts that read and
write text files. Not really bi-directional though.
An ODBC-Pov or a SQL-Pov would be nice for some specialized uses...
