Sybase Assigned Patent

Sybase, Inc., Dublin, CA, has been assigned a patent (8,706,727) developed by Xinjun Yang, Dublin, CA, and Xudong Qian, Shanghai, China, for a “data compression for reducing storage requirements in a database system.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system, method, and computer program product for reducing data storage requirements in a database system are described herein. An embodiment includes identifying at least one data candidate of fixed length data type in at least one row of database data for compression based upon a predetermined threshold level and a boundary of compression, providing at least one bit within the at least one row for an identified data candidate according to the boundary of compression, and storing the at least one row as compressed data in the database system. For compression based on a row boundary, the identified data candidates for compression include fixed length columns having lengths that do not fall below the predetermined threshold level in a row of data and the at least one bit comprises a bitmap for a length of the identified data candidates following compression. For compression based on a page boundary, the identified data candidates for compression include redundant byte string data in a page of data, the redundant byte string data including matching data across columns having lengths that do not exceed the predetermined threshold level.“

The patent application was filed on June 19, 2009 (12/488,022).
