Consider the following schedule that performs actions taken by transactions T1 and T2 on database objects A and B :
T1: S(A), R(A), X(B), U(A), R(B),W(B), Commit: U(B)
T2: S(B), R(B), X(A), U(B), R(A), W(A), Commit: U(A)
Because Strict 2PL is using, this schedule is guaranteed to be conflict serializable.
A: True
B:False
Homework Answers
Answer: True
Explanation: Strict 2PL always guarantees conflict serializability.

Transactions. Consider an ATM system. We have 2 transactions. T1: withdraw $50 and T2: withdraw $100. We consider concurrent executions of the transactions. Which schedule(s) is (are) serializable? Explain why. T2 reads the balance. T1 reads the balance. T2 withdraw $100. T1 withdraw $50. T2 reads the balance. T2 withdraw $100. T1 reads the balance. T1 withdraw $50. T2 reads the balance. T1 reads the balance. T2 withdraw $100. T1 withdraw $50.

2. Given the following three transactions T1 = r1(x); w1(y); T2 = r2(z); r2(y); w2(y); w2(x); T3 = r3(z); w3(x); r3(y); Consider the schedule S = r1(x); r3(z); r2(z); w3(x); r2(y); r3(y); w2(y); w1(y); w2(x); 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 all possible equivalent serial schedule(s).

You are given with the following schedule, that consists of three transactions (T1, T2, T3) and three database elements (A, B and C) w3(A); r1(A); w1(B); r2(B); w2(C); r3(C) a) Identify all the conflicts (as defined in Section 18.2.1 in the book). Hint: draw a bipartite graph between transactions and elements, as done in class b) Draw a precedence graph (as defined in Section 18.2.2 in the book). Is the schedule conflictserializable?
