I don't think that writing it would be your problem - however using it might
I assume that your OLE DB driver would return a set of Heirachal RecordSets
(DataSets) and
in a 3 teir solution these could be heterogenous - The problem
being that most reporting tolls are aimed at RDMS.
If not you could 'group' the 3rd tier objects and present them relationaly.
I was thinking last nite about Pauls comments - (The linetotal =
price*quantity....) and would
you not agree the the 'expression' related to this field is just another
piece of Metadata
In which case it fits neatly into your methodogy of driving the presentation
from
the field metadata
