Abstract: A system and method are provided for reconciling data used by a data management system. The method includes obtaining an input dataset, the input dataset being replicated from a baseline dataset to enable the data management system to operate on the input dataset. The method also includes comparing the input dataset to the baseline data set to determine discrepancies between the input and baseline datasets, by, for each of a plurality of database pools, process data assigned to that pool by concurrently checking for the discrepancies and executing statements without waiting for all pools to have finished processing. The method also includes creating a delta table for each pool to identify extracted data associated with the discrepancies; and combining delta pools from the plurality of database pools and process columns in the delta table.

Abstract: An improved transmission system for a document feeder, in which a constant one-way-rotating gear train is mounted in an output zone so as to cause a transmission shaft in the output zone to rotate in one direction only to send out a sheet of document no matter the driving gear rotates clockwise or counter-clockwise; therefore, as soon as a first sheet of document moves out of the scanning line without moving out of the output zone, the driving gear will change its rotation clockwise so as to have a next sheet of document fed into the scanning zone; therefore, the feeding distance between two sheets of document will be reduced, and consequently the whole feeding time for a document will be reduced, too.
