    Consider the following database schema with tables T1 with column t1 and values (x,z,a), T2 with column t2 and values (b,y) and T3 with column t3 and values (a,b,c). You need to display the matching rows of tables T1 and T2 . The best way is to join T1 and T2; however, there is no common field between these two tables. Write a single SQL query that solves this problem.

    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).
