The database administrator has recently informed you of the
decision to disable certain normalization controls in the
database management system (DBMS) software to provide users
with increased query performance. This will MOST likely
increase the risk of:
A. loss of audit trails.
B. redundancy of data.
C. loss of data integrity.
D. unauthorized access to data.
Answer / guest
Answer: B
Normalization is the removal of redundant data elements from
the database structure. Disabling features of normalization
in relational databases will increase the likelihood of data
redundancy. Audit trails are a feature of DBMS software that
can be lost by not enabling them. These are not connected to
normalization controls. The integrity of data is not
affected directly by disabling normalization controls.
Access to data is set through defining user rights and
controlling access to information, and is not affected by
normalization controls.
