I'd say it depends on performance expectations. When you do
the database magic with grep/sed/awk/cut/tr/bc etc., you can
enclose everything in a sh wrapper. But performance will not
be that good especially for higher input volumes or more
complex algorithms. You can achieve much better results in
using C with the BerkeleyDB interface. Every solution has
its advantages and downsides, though. :-)
