Abstract:
1. A method for reducing data storage requirements in a database system, comprising: identifying, by a computing device, a data candidate of column data specified to be of a fixed length data type property for compression in a row of data having an uncompressed row format of column positioning based on: providing, by the computing device, an offset bitmap for the identified data candidate within the row, according to the boundary of compression, wherein the offset bitmap indicates lengths of compressed columns of the row following compression and variable length columns of the row; and storing, by a computing device, the row containing the offset bitmap for the identified data candidate and the identified data candidate as compressed data with a compressed row format of column positioning within a database system, wherein the compressed row format of the row is repositioned from the uncompressed row format based on the identified data candidate.
