A computer-implemented method for reconciling records from a plurality of data sets includes receiving a first data set from a left data source, retrieving data from the first data set, and placing the retrieved data from the first data set into a first abstract record from the left data source. The method also includes receiving a second data set from a right data source, retrieving data from the second data set, and placing the retrieved data from the second data set into a second abstract record from the right data source. The computer-implemented method also includes comparing the first abstract record and the second abstract record.
