T1 = r1(x); r1(y); w1(z);
T2 = r2(x); w2(x); w2(y);
T3 = r3(y); w3(z);
Consider the schedule S = r1(x); r2(x); r3(y); r1(y); w3(z); w2(x); w2(y); w1(z);
a. Draw the precedence graph of schedule S., and label each edge with data item(s).
b.Based on the precedence graph, determine whether S is conflict serializable and justify your answer. If it is serializable, specify the equivalent serial schedule
These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.a). We must first identify conflicting pairs on the same resource performed by different transactions.
• Read after Write conflicts – there is no such
• Write after Read conflict:
a). W2(X) after R1(X) => we draw an edge T1 --> T2
b). W2(Y) after R3(Y) => we draw an edge T3 --> T2...
