Question
Given the following transaction T: A = 1 and B = 2 at the start of the execution T R(A) R(B) A: = A+B B:
Given the following transaction T:
A = 1 and B = 2 at the start of the execution
| T | R(A) | R(B) | A: = A+B | B: = A+B | COMMIT |
We run this transaction on a database that does not guarantee Durability. If our computer crashes after committing T, what are the possible values of A and B after it restarts?
