It's probably the Network Administrator inside of me speaking, but all I can say is "Typical DB Engineer article..." Completely overlooking the security of sensitive data. It is the responsibility of the Engineer to design the database in such a manner to maintain the integrity of the secure data. Stored procedures should be created to simplify the management of the database. Granted the Project Manager or DB Manager should be aware of security when the database is integrated into the system, the DB Engineer needs to either design the database with security in mind or document steps for the integration/management team to ensure security.
