Hi Nadya

E.g. I glanced at it yesterday and noticed the loop through array of relations. In our current database we have 252 relations (sic!) ...

uuuuuuf !
This sound to me as problematic design ...

252 persistent relations ?!?
How many tables you hv ??
How big is DBC itself ??

It seems to me that you guys are inn for maintenance nightmare.
Was'nt it better spliting it in few smaller DBCs ?

That RI builder of yours better be good :)

Good luck
