Claim 13:
14. The method of claim 8, wherein the system further includes a transaction manager node, the method further comprising:
generating, by the transaction manager node, a root transaction start identifier of a root transaction, associated with the data of the dataset, under which the statement-level transaction having the statement-level identifier is nested, the root transaction start identifier being based on a value of a system counter;
wherein values of statement-level identifiers, values of vertex-level identifiers, and values of task-level identifiers comprise transaction identifiers, are uniquely generated under their respective parent identifiers based on counters therefor, and are stored in corresponding rows of the data as stored versions in response to local commits; and
wherein the data visibility rules are enforced in the system for nested transaction levels based at least on a comparison of the stored versions with at least one of the transaction identifiers.
