Method, system, and program for determining whether data has been modified
First Claim
1. A computer implemented method for determining whether data has been modified, comprising:
- receiving one node associated with at least one data unit and a last version number;
processing a data structure having a plurality of nodes, wherein there is one node associated with each data unit and at least one node that is capable of aggregating one or more nodes, wherein version numbers are associated with the nodes;
determining from the data structure one node that is associated with the data units associated with the received node; and
determining that the at least one data unit associated with the received node has been modified if the received last version number is less than a version number of the determined node.

Abstract
Provided are a method, system, and program for determining whether data has been modified. One node associated with at least one data unit and a last version number is received. A data structure having a plurality of nodes is processed, wherein there is one node associated with each data unit and at least one node that is capable of aggregating one or more nodes, and wherein version numbers are associated with the nodes. A determination is made from the data structure of one node that is associated with the data units associated with the received node. A determination is then made that at least one data unit associated with the received node has been modified if the received last version number is less than a version number of the determined node.

26. An article of manufacture computer implemented method for determining whether data has been modified, wherein the article of manufacture causes operations to be performed, the operations comprising:
-
receiving one node associated with at least one data unit and a last version number;
processing a data structure having a plurality of nodes, wherein there is one node associated with each data unit and at least one node that is capable of aggregating one or more nodes, wherein version numbers are associated with the nodes;
determining from the data structure one node that is associated with the data units associated with the received node; and
determining that the at least one data unit associated with the received node has been modified if the received last version number is less than a version number of the determined node. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
