Suppose relation R(a,b,c) has the following tuples: (1,1,3), (1,2,3), (2,1,4), (2,3,5), (2,4,1), (3,2,4), and (3,3,6). Determine the result of the following query: SELECT V.d, SUM(V.c) FROM (SELECT a+b AS d, R.c GROUP BY V.d HAVING COUNT(*) <> 1; Which of the following tuples is in the result set? O a. (3, 12) O b. (3,6) FROM R)AS V O c. (5, 7) O d. (6, 7)

A table called "game1" contains three columns and twenty rows, but "game2" has the same column as game1 (ie 3) and fifteen rows. Both tables have 5 rows in common. What is the degree and cardinality of the resulting table if we take union?
Consider the following scenario: you have a relation that contains x, y coordinates, and the names of eateries. Assume, further, that the only questions that will be asked will be of the following types. The query specifies a location and inquires as to whether or not there is a restaurant located exactly at that location. If you were to choose between R-Tree and B-tree, which one would you choose? Why?
What does a TRC query mean? More precisely, what is the set of answer tuples for a given TRC query? The answer to a TRC query {T| p(T)}, as we noted earlier, is the set of all tuples t for which the formula p(T) evaluates to true with variable T assigned the tuple value t. To complete this definition, we must state which assignments of tuple values to the free variables in a formula make the formula evaluate to true.

The recurrence relation of the divide phase of merge function is T(n)=2T(n/2) and merge as O(n). The illustration for the divide phase is shown below. If the recurrence relation is to be made as T(n)=4T(n/2) and merge as O(logn), would this be better or worse than the original merge function? Why(please explainin detail)? Please also provide the illustration for the divide phase of the modified merge function.
30 of 40 Let T(a,b,c) be a relation in which attribute a is not NULL. Consider the SQL query: SELECT * FROM T Tcopy WHERE a NOT IN (SELECT a FROM T WHERE Tcopy.a>10 ); Which of the following RA queries produces the same result as the SQL query above? Select one: O Ja>10(Ta.b.c (T)) O Ja10 (T))
What is the output of an operation that begins with the execution of a Cartesian product of student and adviser and then continues with a selection operation on the result using the predicate s id = ID? Using the symbolic notation of relational algebra, this query may be expressed as s id=ID if it is given in that format (student advisor).
When a relation is partitioned on one of its properties by: a. Hash partitioning, what factors could cause skew? What about range partitioning? What can be done in each scenario to lessen the skew?
