A database View operation implements the principle of:

A.
Entity integrity.

B.
Separation of duties.

C.
Referential integrity.

D.
Least privilege.

Explanation:
The correct answer is “Least privilege”. Least privilege, in the database context, requires that
subjects be granted the most restricted set of access privileges to the data in the database that are
consistent with the performance of their tasks. Separation of duties, assigns parts of securitysensitive tasks to several individuals. Entity integrity requires that each row in the relation table
must have a non-NULL attribute. Relational integrity, answer d, refers to the requirement that for
any foreign key attribute, the referenced relation must have the same value for its primary key.
