Explanation: A relational database table is often described as “normalized” if it is in the Third Normal Form because most of the 3NF tables are free of insertion, update, and deletion anomalies . 8. Relation R with an associated set of functional dependencies, F, is decomposed into BCNF. The redundancy (arising out of functional dependencies) in the resulting set of relations is
A. Zero
B. More than zero but less than that of an equivalent 3NF decomposition
C. Proportional to the size of F+
D. Indeterminate
Answer:A

Explanation:Redundancy in BCNF is low when compared to 3NF. For more details on BCNF . 9. A table has fields F1, F2, F3, F4, and F5, with the following functional dependencies:
