I can't prove that right now but I believe more than %90 of your
potential readers will have touched some RDBMS (MySQL, PostgreSQL,
MS SQL Server, Oracle, etc.) and played with SQL and stored
procedures in some way.

So, assuming a hypothetical database (one of the most popular
ones mentioned above) and a couple of tables created and not
explaining how to install and create a database from scratch
wouldn't hurt too much.

I'm sure if you add that to the 2nd Edition and on the backcover
tell people that you are showing them how to connect to RDBMS, pull any kind
of data and publish them, this would increase book's popularity.
Just like the familiar terms like MP3, streaming, Shoutcast server,
HTML, Internet programming, etc. do (ok, I accept that connecting
to RDBMS stuff is trivial, not half interesting as MP3 stuff but
it gives you more and more chance for "yes, Common Lisp for real world
problems, what else did you think?" :)


Happy hacking,
