Best way to process table rows from an RDBMS

[dananrg at yahoo.com]

I can handle making the connections and running queries, but what's the
best way to process table rows returned in Python? What about turning a
table definition into an object? Just looking for ways to be efficient,
since I know I will be hitting the same external RDBMS from Python and
regularly processing a fixed set of tables with a certain fixed set of
attribute columns.

Is there something better than tuples for this?
