Question

Help would be greatly appreciated

Mark each of the statements below as True (T) or False (F).

[     ]  The main problem with “bushy” query trees is that there are so many possible combinations and sequences of doing the joins that it becomes prohibitively expensive (time-consuming) to consider and evaluate them all.

[     ]   It is always faster and more efficient to use an index on a particular column if one is available, regardless of the particular selection criteria.

Answer 1

1. True
2. True
