I've been reading the Huggins and Staudte paper, "Variance Components Models for Dependent Cell Populations", from the Journal of the American Statistical Association, 1994.

I have the following problem, a legacy Oracle database with partitioned indexes. Every single table has a column that specifies the partition. So my current thinking is to add a route section to the url that specifies the partition (this also makes business sense-- it''s the way URLs are currently formed). Next make a modification to the ActiveRecord, and a lib that for all selects,
