1 (a)How would distributed 2PL transaction manager and lock manager algorithms change if a distributed computational model was used.

1 (a)How would distributed 2PL transaction manager and lock manager algorithms change if a distributed computational model was used.

2.(b)Briefly compare and contrast the centralized 2PL and the distributed 2PL in terms of cost to applications

1(a) If the distributed computational model was used, that means the transaction taking placeis made from the nested transaction model that is the good indicator of distributed executionmodel....
