Abstract
Aspects described herein relate to methods and systems for comparing data stored in disparate parallel systems using hash sums. A database having a parallel system architecture may comprise a plurality of nodes each storing a plurality of records. A central node may initiate parallel calculation of a set of node hash sums for each individual node. Calculating a node hash sum for an individual node may comprise calculating, by the individual node, a set of hash values for each individual record of the plurality of records stored by the individual node and combining each hash value of the set of hash values to generate the node hash sum for the individual node. The central processor may combine each node hash sum to generate a database hash sum. The central processor may store the generated database hash sum and/or utilize it in comparisons with database hash sums for other databases.
