Let Q ={q1,...,q5} be a set of queries, A ={A1,..., A5} be a set of attributes, and S ={S1,S2,S3} be a set of sites. The matrix of Fig. 2.25a describes the attribute usage values and the matrix of Fig. 2.25b gives the application access frequencies. Assume that refi(qk) =1forall qk and Si and that A1 is the key attribute. Use the bond energy and vertical partitioning

Transcribed Image Text:### Educational Resource: Matrix Representation
#### Figure (a): Incidence Matrix
The matrix in Figure (a) is an incidence matrix that displays the relationship between sets of elements, \( A_1, A_2, A_3, A_4, A_5 \), and \( q_1, q_2, q_3, q_4, q_5 \). Each row represents a different element \( q_i \), and each column represents an element \( A_j \). A value of '1' indicates the presence of a relationship between the corresponding elements, and '0' indicates no relationship.
- **Row \( q_1 \):** \( A_2, A_3, A_5 \)
- **Row \( q_2 \):** \( A_1, A_3, A_5 \)
- **Row \( q_3 \):** \( A_2, A_4 \)
- **Row \( q_4 \):** \( A_3 \)
- **Row \( q_5 \):** \( A_1, A_2, A_3 \)
#### Figure (b): Transaction Matrix
The matrix in Figure (b) represents a transaction matrix showing interactions or values (\( S_1, S_2, S_3 \)) across different entities \( q_1, q_2, q_3, q_4, q_5 \). Each entry provides a quantitative representation of the relation.
- **Row \( q_1 \):** \( S_1 = 10 \), \( S_2 = 20 \), \( S_3 = 0 \)
- **Row \( q_2 \):** \( S_1 = 5 \), \( S_2 = 0 \), \( S_3 = 10 \)
- **Row \( q_3 \):** \( S_1 = 0 \), \( S_2 = 35 \), \( S_3 = 5 \)
- **Row \( q_4 \):** \( S_1 = 0 \), \( S_2 = 10 \), \( S_3 = 0 \)
- **Row \( q_5 \):** \( S_1 = 0 \), \( S_2 = 15 \), \( S_3 = 0 \)
