Just a quick note to relate an experience I had with a DBC.

My design had a table in the dbc which contained 214 fields. I was in the middle of my intial development (read - not yet backed up!) when I had a crash which corrupted the dbc. When I recovered the table (I had to destroy the link) all the field names which were longer than 10 characters had been truncated. Some field names were identical to 10 characters so I was getting duplicate field name errors. Moral - back up often or dont use the long name option in the dbc.
