Frank, have you had any others look at your data model - assuming it's not a
trade secret - in order to assess how well normalized it is?  I've found in
just about every case, the more a model is normalized, the less space it
requires on disk.

Additionally, I think there are some RB developers in the Chicago-land area
who might be induced to dialogue w/you about this.

Just some thoughts,
Steve in Memphis
