The MySQL Command Line client is the only utility installed with the MySQL community edition installation, even though dozens of GUI interfaces exist to fill in the void, from commercial to free and open source, in virtually every programming language out there. This variety attests to the popularity of this open source relational database. Here we are going to use the built-in Command Line Client (of course, you can always use SQuirreL Universal SQL Client's GUI to do visual installation; check the resources available at the book's support site, www.wrox.com, and www.agilitator.com).
MySQL GUI tools, long-time staples of the MySQL community, are being discontinued, and the new MySQL Workbench is currently available for download as free Community Edition (CE). This is yet another application to be installed and configured, and I've decided to leave it out for now. Check the book's support website at both www.wrox.com and www.agilitator.com for updated tutorials, or go to tool's website: http://wb.mysql.com/.
