5. The method of claim 1 , wherein the set of characteristics includes aggregate statistical characteristics comprising at least one of generic aggregate statistics and scenario aggregate statistics, wherein the generic aggregate statistics are calculated in a manner that is independent of a set of semantics of the attributes, and wherein the scenario aggregate statistics are defined through a domain expert and are relevant in a particular scenario to enable incorporation of a domain-specific interpretation of semantics of each attribute and each set of data of the at least one of the initial result set and the subsequent result set.

The method of claim 5 , wherein the scenario aggregate statistics are programmed via user-defined aggregate queries associated with the at least one of the initial result set and the subsequent result set, wherein a syntax of the user-defined aggregate queries is specific to a standard query processing engine, and wherein a signature of the scenario aggregate statistics creates a signature that corresponds to a set of table valued functions.
