2. The method of claim 1 , wherein the set of characteristics includes metadata of the initial query comprising at least one of: a number of attributes in the initial result set, a data type of each of the attributes, a frequency of usage per user, a uniqueness constraint on the attributes, anullability of individual attributes, and a functional dependency between the attributes.

The method of claim 2 , 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 the semantics of the each attribute and each set of data of the at least one of the initial result set and the subsequent result set.
