METHOD AND SYSTEM FOR FAST DATA COMPARISON USING ACCELERATED AND INCREMENTALLY SYNCHRONIZED CYCLIC DATA TRAVERSAL ALGORITHM

摘要

A computer-implemented method and system for providing fast data comparison of large datasets for one or more huge-sized heterogeneous database are disclosed. A source database and a target database are selected from one or more databases. A source dataset and a target dataset are extracted from the selected source database and the target database respectively. Each dataset comprises a plurality of data-strings and each data string is assigned a unique key that facilitates in generating a sequenced-file cache. The data of the cache is read incrementally in order to perform a fast data comparison between the source dataset and the target dataset.
