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?
