So I started this book and I am stuck on the first chapter. I feel really lame. I can't get a connection for the database. I am confused on some of the connection info:

define('DB_SCHEMA', 'WROX_DATABASE');
define('DB_TBL_PREFIX', 'WROX_');

Where do I find the DB_SCHEMA and the DB_TBL_PREFIX (Ithink I know the prefix)

I use go daddy for hosting and I imported the database the book code had.
