5603022 - Data compression system and method representing records as differences between sorted domain ordinals representing field values - Owned by The Regents of the University of Michigan (Ann Arbor, MI)

Records in the relational database are converted into ordinal numbers. The numbers are then sorted by a predetermined ordering rule. Next, for each record, the difference between the number and the preceding number is computed and this difference is then used to represent that record. The compression technique results in highly compressed data that can still be handled by conventional relational database software for record insertion, deletion and other standard database operations.

5678043 - Data compression and encryption system and method representing records as differences between sorted domain ordinals that represent field values - Owned by The Regents of the University of Michigan (Ann Arbor, MI) [*] Notice:The portion of the term of this patent subsequent to September 23, 2014 has been disclaimed.

Records in the relational database are converted into ordinal numbers. The numbers are then sorted by a predetermined ordering rule. Next, for each record, the difference between the number and the preceding number is computed and this difference is then used to represent that record. Alternatively, for each record, the difference between the number and some other record's number that is within the same block is computed and the difference is then used to represent that record. The compression technique results in highly compressed data that can still be handled by conventional relational database software for record insertion, deletion and other standard database operations.
