If I might add to this wonderful tut (great job), if you are lazy and don't want to copy and paste or, heaven forbid, type the SQL commands one by one, you can copy all of those commands posted above into notepad, then save it as a .sql file... then install
Navicat front-end (for MySQL) and after setting it up to connect to your db (very easy) right click on your peq db (or ax, or whatever you named it) in the gui then, from the pop-up menu click "execute batch file" and select your .sql file from the pop-up file browser.....
Just thought that might make things a little easier to digest...:P
