SYSTEM AND METHOD FOR GRANULAR SCALABILITY IN ANALYTICAL DATA PROCESSING

摘要

A method of resolving data queries in a data processing system. The method comprises receiving in the data processing system a data query, where the data processing system stores a plurality of information units describing pluralities of data elements, a first information unit having a retrieval subunit that includes information for retrieving all unique data elements in a first plurality of data elements and a summary subunit including summarized information about data elements in the first plurality of data elements. The method further includes deriving, via the data processing system, a result of the data query, wherein the result of the data query comprises a plurality of new data elements. The data processing system uses summary subunits of information units to select a set of information units describing data elements that are sufficient to resolve the data query.

1. A method of resolving data queries in a data processing system, the method comprising:
receiving in the data processing system a data query, wherein the data processing system stores a plurality of information units describing pluralities of data elements, a first information unit having a retrieval subunit that includes information for retrieving all unique data elements in a first plurality of data elements and a summary subunit including summarized information about data elements in the first plurality of data elements; deriving via the data processing system a result of the data query, wherein the result of the data query comprises a plurality of new data elements, and wherein the data processing system uses
summary subunits of information units to select a set of information units describing data elements that are sufficient to resolve the data query,retrieval subunits of information units in the selected set of information units to retrieve data elements sufficient to resolve the data query, andretrieved data elements and summary subunits of information units stored by the data processing system to resolve the data query; and returning the result of the data query.
