1. What is the purpose of db_denydatawriter and db_denydatareader?

The deny roles are an extra safeguard that you can use to make sure that certain logins or groups will never have the type of access that is specifically denied under the role. With nesting of groups in Windows and multiple role assignments sometimes individuals inadvertently end up with excessive permissions. This is just another level that can be applied to lessen these accidental cracks in the permissions hierarchy.
