The data
You will find the information you need to set up MySql at: http://dev.mysql.com/
The file allbatch.txt which is included in the catalog of this demosite, contains all the sql-commands you need to establish the database football. Inspect it and remove the drop-statement (first line) first time you run it.
Run it against the database, with a command like:
mysql -h localhost -u root -p < c:\wxt\wxtdemo3\allbatch.txt
assuming that you have unpacked this demo in c:\wxt\wxtdemo3
