Patent Document ID: 9292568
Application ID: 13648903

Base Claim:
1. A method of query optimization, comprising: comparing a complexity measure of a client query received from a client application to a predetermined threshold, wherein the predetermined threshold is determined based on query execution data collected from a previous query; generating an optimized query by automatically modifying the client query without user input to reduce the complexity measure of the client query if the complexity measure of the client query exceeds the predetermined threshold; submitting the optimized query to a server application on a server; selecting a post-processing routine to be applied to a result set of the optimized query; applying the post-processing routine to the result set of the optimized query to generate a filtered result set; and forwarding the filtered result set to the client application.

Claim 4:
4. The method of claim 1 , wherein the query execution data comprises, for at least one previously executed query, at least one of a result set size, a query response time, a query execution time, a measure of the network load at the time of query execution, and a query complexity measure.
