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.
