SECTION B Write SECTION B: Question B2, your name and student ID on the top of the first page of your answer to this question. QUESTION B2. (9 marks) Consider a database with objects A and B, and the following two transactions $T_1$ and $T_2$ involving those objects: T1: begin_transaction read(A); read(B); if A=0, then B:= B+1; write(B); end_transaction T2: begin_transaction read (B); read(A); if B=0, then A:= A+1; write(A); end_transaction Let the initial values of A and B be 0. Also let the consistency requirement be: either A = 0 or B = 0. (a) (2 marks) Show that every serial execution of these two transactions preserves the consistency of the database. (b) (3 marks) Construct a concurrent execution of T1 and T2 that produces a nonserializ- able schedule. (c) (4 marks) Explain what conflict serializability means, and how two-phase locking pro- tocol (2PL) guarantees it. Place suitable lock instructions in $T_1$ and $T_2$ so that they follow the 2PL protocol.
