data node

I'm a newcomer to Drupal (about three weeks in) and I'm struggling a bit with using the Data module with Taxonomy. As a bit of background, I'm trying to develop a data reporting mechanism where, each value entered is associated with the deepest level of a taxonomy vocabulary. For example, a user would submit the number of cases closed during that quarter, disaggregated by Location > Department > Floor > Title. I originally started building this using CCK for data capture, and using node relationship to pull together my views for reporting.
