Pablo Diaz Gutierrez, Vijayshankar Raman, Garret Swart: Method for compressed data with reduced dictionary sizes by coding value prefixes. International Business Machines Corporation, IP Authority, Ramraj Soundararajan, October 27, 2009: US07609179 (90 worldwide citation)

The speed of dictionary based decompression is limited by the cost of accessing random values in the dictionary. If the size of the dictionary can be limited so it fits into cache, decompression is made to be CPU bound rather than memory bound. To achieve this, a value prefix coding scheme is presen ...

Craig Alan Friske, John Marland Garth, Christina Marie Lee, James Ruddy: Method and apparatus for building one or more indexes on data concurrent with manipulation of data. International Business Machines Corporation, IP Authority, Ramraj Soundararajan, December 11, 2007: US07308456 (36 worldwide citation)

One or more indexes are built on data (concurrent with manipulation of data) wherein the index build operation is done without restricting the manipulation of data. The index is brought to consistency with the data based upon processing recovery log records to simulate index manipulations during dat ...
