Abstract: A method comprises grouping, via a data processing system, a plurality of data elements in a same data type into a plurality of data units. The method further comprises gathering, via the data processing system, information about data elements in a first data unit into a first information unit. The first information unit comprising a representation of information that is less than all unique information in the first data unit. The method also comprises storing, via the data processing system, the first information unit on a computer readable storage device. The method additionally comprises identifying, via the data processing system, based at least in part on the first information unit, whether the data elements in the first data unit are required to be retrieved to resolve a first data query received by the data processing system and to resolve the first data query.

Abstract: A system and method of processing a data query in a data processing system is provided. The data in the data processing system includes a plurality of individual data elements. The data elements are grouped and stored in at least one data unit. The information about the at least one data unit is gathered and stored in at least one information unit. The method comprises receiving the data query to be executed; using the information in the at least one information unit to optimize and execute the query; resolving the data query; and returning results of the data query for use by the data processing system.

Abstract: A method for applying adaptive data compression in a relational database system using a filter cascade having at least one compression filter stage in the filter cascade. The method comprises applying a data filter associated with the compression filter stage to the data input to produce reconstruction information and filtered data, then compressing the reconstruction information to be included in a filter stream. The filtered data is provided as a compression filter stage output. The method may comprise evaluating whether the compression filter stage provides improved compression compared to the data input. The filter stage output may be used as the input of a subsequent compression filter stage.
