My experience has been that the additional code adds a huge overhead as
the data size increases. In an application I wrote at Polaroid, when I was
just beginning to dabble in SQL, I kept the SQL simple and wrote the
hairier pieces in perl, and the application didn't scale well to 1000
records. When I reimplemented those parts in SQL, it scaled comfortably to
10,000 records, and performed about 1000 times faster than the prior
version with 1000 records.
