|
Every Boyce-Codd Normal Form(BCNF) decomposition is
|
dependency preserving
|
|
|
not dependency preserving
|
|
|
need not be dependency preserving
|
|
|
none of these
|
Question 3 Explanation:
Normalization requires definitely loss less decomposition but not dependency preserving. But BCNF need to be functional dependency.
