This problem is based on tables T1 and T2 from Elmasri Figure 8.15 (this is Figure 6.15 in some earlier editions) ; this figure is also in the powerpoint notes. For each of the following relational algebra queries, show the output table (no explanations needed : just show the table): (a) T1 ./T1.P T2.A T2 (b) T1 ./T1.R T2.C T2 (c) T1 ./T1.R T2.C AND T1.P = T2.A T2
