26. The computer program product of claim 25 , wherein the code for identifying the set of quota cells further includes code for traversing the graph database to identify a set of the quota cell vertices each having at least one includes type of edge that encounters at least one of the profile parameter value vertices identified for the panelist, and that do not have at least one excludes type of edge that encounters at least one of the profile parameter value vertices identified for the panelist.
25. The computer program product of claim 24 , wherein a code for identifying a set of quota cells includes code for traversing edges of the graph database from a panelist vertex to all profile parameter value vertices of the graph database representing profile parameter values that have been identified for a panelist represented by the panelist vertex.
