For these questions, there exists 4 relations: R(A,B,C), S(C,D), T(D,E,F), and U(B,G). The size of attributes A to D are 10 bytes each, attributes E and F have size 100 bytes, and attribute G has size 1000 bytes. The blocks size is 16,384 bytes with no spanning. Relation R has 100,000 tuples, relation S has 20,000 typles, T has 5,000 tuples, and relation U has 150,000 tuples. Other statistics: V(R,C)=10,000, V(S,D)=500, V(R,B)=1000. Assume that attributes with the same name can be joined across relations (and duplicates are eliminated during a join), and the first attribute is the primary key of the relation. Answer the following questions about calculating intermediate result sizes. Answer the question in terms of the # of tuples and the # of blocks. Question 3 What is the size of op=10(S)? Tuples: Blocks:

For these questions, there exists 4 relations: R(A, B,C), S(C,D), T(D,E,F), and U(B,G). The size of attributes A to D are 10 bytes each, attributes E and F have size 100 bytes, and attribute G has size 1000 bytes. The blocks size is 16,384 bytes with no spanning. Relation R has 100,000 tuples, relation S has 20,000 typles, T has 5,000 tuples, and relation U has 150,000 tuples. Other statistics: V(R,C)=10,000, V(S,D)=500, V(R,B)=1000. Assume that attributes with the same name can be joined across relations (and duplicates are eliminated during a join), and the fırst attribute is the primary key of the relation. Answer the following questions about calculating intermediate result sizes. Answer the question in terms of the # of tuples and the # of blocks. Question 3 What is the size of op=10(S)?
