While I also would use MySQL or Postgresql for something like this it really doesn't matter. How to organize the data doesn't matter either.

Stamp_Guy, I would recommend just focusing on organizing the data so it's most convenient for you to implement the search features you need. If the site gets less than a few hits per second, then with only 500 entries in the database it'll be super fast no matter how you do it. How big is the whole database? If you run mod_perl you could actually use Storable and just load the whole thing into memory every time the file gets updated (although with DB_File and BerkeleyDB you can get either shared memory BerkeleyDB foo and/or the filesystem cache).

But I digress; the point is that all that doesn't matter. Save the fancy design for when you need it. Focus on getting the thing done and implementing the needed functionality.
