U.S., Canadian Inventors Develop Data Warehouse Management Method

ALEXANDRIA, Va., May 9 -- Kevin Leo Beck and Paul Michael Brett, both of Portland, Ore., Jeffrey James Goss of Toronto, Dieu Quang La of Markham, Canada, Catherine Suzanne McArthur of Uxbridge, Canada, and William T. O'Connell of Etobicoke, Canada, have developed a method for managing a data warehouse.

According to the U.S. Patent & Trademark Office, the invention relates to a "system and a method for the deferral and incremental performance of integrity processing for data rolled into a table of a data warehouse and for the deferral and incremental performance of maintenance on data rolled out of a table of the data warehouse while permitting general users online access to other data contained in the table. The rolled in and rolled out data are contained within specific data partitions of the table. Each data partition in the table has an associated distinguishable partition identity. Each data partition can also have associated attributes corresponding to containing rolled-in and rolled-out data respectively. Table operation mechanisms are arranged such that general users of the table do not access rolled in data in a partition for which integrity processing has not yet been performed and do not access rolled out data."

The inventors were issued U.S. Patent No. 7,359,923 on April 15.

The patent has been assigned to International Business Machines Corp., Armonk, N.Y.

The original application was filed on Aug. 20, 2004, and is available at: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=7,359,923.PN.&OS=PN/7,359,923&RS=PN/7,359,923.
