1. A method for query processing in a grid computing infrastructure, comprising:
- storing data in a data storage system accessible to a plurality of individual computing nodes;
identifying specified query operations;
allocating query fragments of a specified query operation to the individual computing nodes according to each of the individual computing nodes computing capability;
independently executing the query fragments on the individual computing nodes in parallel to increase speed of query execution; and
combining the query fragment results into a final query result.

Abstract
A method is provided for query processing in a grid computing infrastructure. The method entails storing data in a data storage system accessible to a plurality of computing nodes. Computationally-expensive query operations are identified and query fragments are allocated to individual nodes according to computing capability. The query fragments are independently executed on individual nodes. The query fragment results are combined into a final query result.
