There are three transactions in the queue:

For ID$=1$ change the value in the attribute Department to $$Music$.$

For ID$=5$ change the value of the attribute Civil$-$status to $$Divorced$.$

for ID$=15$ change the value of the attribute Salary to $200000.$

Note

Transactions are satisfactorily completed ONLY when a commit has occurred.

If one is processing transaction No$.2$ and an error occurs, the rest of the transactions in the

list $-$those not processed yet$-$ will be ignored $($we are doing this to make the problem

simpler$).$

As the simulated failure occurs randomly, you may have to run your code several times until

a failure happens.
