I see this as useful (with some modification) for deciphering Microsoft SharePoint content databases, which are de-normalized to provide generic functionality.

When I create a list in SharePoint and want to get at that list data outside of the SharePoint API I create views, but have figure out what generic column was assigned to hold my data. This is a very tedious task, and if I move the list to another site I have to manually re-map the view.

I can in theory use this type of script to find the columns by creating a control row with specific values, and then run this util to determine the column names.
