- Consider the following two transactions:T13: read(A);read(B);if A = 0 then B := B + 1;write(B).T14: read(B);read(A);if B = 0 then A := A + 1;write(A). Let the consistency requirement be A = 0 ∨ B = 0, with A = B = 0 as the initial values. a. Show that every serial execution involving these two transactions preserves the consistency of the database. b. Show a concurrent execution of T13 and T14 that produces a nonserializable schedule. c. Is there a concurrent execution of T13 and T14 that produces a serializable schedule?Consider the following two transactions: (SHOW WORK) T13: read(A); read(B); if A = 1 then B := B - 1; write(B). T14: read(B); read(A); if B = 1 then A := A - 1; write(A). Let the consistency requirement be A = 1 or B = 1, with A = 1 and B = 1 as the initial values.a.

Working steps must be shown.
- Consider that a database contains the following relations PARENT(X, Y), and a relation BIRTH(X, B), where B is the birthdate of a person X. The following information is used for question (b), (c) that we have the following family treeGiven the following transaction database from a supermarket: Transaction ID items T1 I1, I2, I3 T2 I2, I3, I4 T3 I4, I5 T4 I1, I2, I4 T5 I1, I2, I3, I5 T6 I1, I2, I3, I4 What is the output of the Apriori algorithm run on the above transaction database with a minimum support of 50 % (i.e. 3 out of 6 transactions)? Calculate the following confidence: {I1, I2} => { I3} {I2} => {I1, I3} {I1, I3} => {I2} Calculate the following lift: {I2} => {I3} {I2} => {I4} {I1, I3} => {I2}2.

- Suppose we have market basket data consisting of 100 transactions and 20 items. Compute the total number of possible association rules. If the support for item A is 25%, the support for item B is 90% and the support for itemset {A,B} is 20%. Let the support and confidence thresholds be 10% and 60%, respectively. Compute the confidence of the association rule {A} → {B} & {B} → {A}. Consider the following data of software repository which represents set of source files changed together in six different transactions (TID). Transaction is an event in which developers change one or more source files together to incorporate changes in software. Table-1 TID Items (source files change together) 1 File1, File2, File3 2 File1, File2 3 File1, File4, File5 4 File5, File4 5 File5, File3 6 File1, File4, File5 Use Table-1 data and apply APRIORI algorithm to find the most frequent association rules which can…Consider a database system that includes an atomic increment operation, in addition to the read and write operations. Let V be the value of data item X.The operation increment(X) by C sets the value of X to V + C in an atomic step. The value of X is not available to the transaction unless the latter executes a read(X).Assume that increment operations lock the item in increment mode using the compatibility matrix in Figure 18.25.a. Show that, if all transactions lock the data that they access in the corresponding mode, then two-phase locking ensures serializability.b. Show that the inclusion of increment mode locks allows for increasedconcurrency.Consider the database containing transaction data as shown in the table below. Apply Apriori algorithm and find the frequent itemsets where min-sup=2. TID Items Bought 1 Daiper, Bread, Juice 2 Eggs, Bread, Pasta 3 Daiper, Eggs, Bread, Pasta 4 Eggs, Pasta 5 Rice
