Andrew Cumming is the Zoo Keeper at http://sqlzoo.net. He keeps a collection of tame SQL engines and presents these to the public. He cares for these beasts, protecting them from the abuse inflicted by SQL learners, and protecting SQL learners from the injuries that the wild engines can inflict. But mostly he shovels manure out the cages and hoses them down every now and then. Andrew also teaches at Napier University in Edinburgh, Scotland.Dr. Gordon Russell is a Computing lecturer in Napier University, Scotland. He teaches databases, Linux, and networking. He also builds educational websites, concentrating on technology-driven online learning environments. These include db.grussell.org, whose claim-to-fame is its automatic checking of SQL assessments, and linuxzoo.net, which offers online users root free access to Linux servers. But without database technology to support these sites, even he would be lost.
