14. A non-transitory computer-readable medium having stored thereon in a fixed tangible form instructions when executed by the processor to cause the processor to carry-out steps: determining whether data specifying information meets a first criterion or a second criterion, with the data specifying information included in a WHERE clause of a SELECT statement, with the data specifying information specifying data in the database that is the subject of the SELECT statement; triggering a first resource group specification if the information included in the WHERE clause meets the first criterion, where the first resource group specification allocates a first set of processing resources of the processing system; triggering a second resource group specification if the information included in the WHERE clause meets the second criterion, where the second resource group specification allocates a second set of processing resources of the processing system; and processing the SELECT statement using either the first set of processing resources or the second set of processing resources based on which resource group specification is triggered.

The non-transitory computer-readable medium as recited in claim 14 wherein the first resource group allocates a resource based upon a time interval between an I/O access of the data, a database query and an identification of a user that initiates the database query.
