availability, is negative in a database environment because it demands additional

and otherwise unnecessary data handling efforts. Denormalization is sometimes

advisable for functional reasons.




C. Denormalization pertains to the structure of the database, not the access

controls. It should not result in unauthorized access.




D. Denormalization may require some changes to the calls between databases and
