Give a complete description of an algorithm for a parallel validation, optimistic concurrency control.

What will be an ideal response?


1. If the read phase of T1 overlaps the validation/write phase of T2, then if the set
of items read by T1 is not disjoint from the set written by T2, abort T1.
2. If T1 enters its validation/write phase after T2 and the execution of those phases
overlap, then if the set of items written by T1 is not disjoint from the set written
by T2, abort T1.
3. If T1 has not been aborted because of (1) or (2), commit T1.
