I have been resesarching this issue and realised that you cannot force referential integrity using a myisam database engine. Unfortunately I am using a myisam database engine. Did you use a innodb database engine to create the blue sky music database?. If not how did you (do you) force referential integrity using a myisam engine?

Secondly did you need to force referential integrity on any of the relationships in the blue sky music database?

Items.ItemcatID is a forign key relation to itemcategory.ItemcatID

orderdetails.DetailOrderID is a foreign key relation to orders.OrderID

orders.OrderStatus is a foreign key relation to orderstatustypes.StatusID

visitors.VisitorGroupID is a foreign key relation to groups.GroupID

If so could you please describe to me in detail how you do it? (sql statement)
