I'm not arguing that the dbase isn't the way to go, but if you wanted
to do the manipulations in python, the Numeric package certainly
provides the speed you need to manipulate large quantities of data
rapidly.  I sometimes use a C extension to put data from an SQL
database directly into Numeric arrays and then manipulate the data in
python.
