Sorry I have just started to use and understand drupal

Is it possible to have 2d structuring of content with drupal. What I mean is there are two ways in which content can described . So all content is divided into one

major structure

A B and C

and A has a minor structure x , y z

and B has i,jk

I need to able to do some kind of rendering in both , Can one do that through drupal.
