Patent ID: 7200607

Claim:
A database analysis system comprising: a store for storing databases, a user input and a user output, and a processor, wherein the store comprises a first database having a plurality of records of prospective customers, each record comprising predictor variables being discretely identifiable in separate fields, each field being catagorised into two or more categories, the store further comprising a second database of responders comprising a plurality of records of predictor variables of selected customers, wherein the processor is adapted to compare the predictor variables for each of the records in the first and the second databases and to generate an output to the user to enable the user to view a comparative result, wherein the records of the first database are compared to the records of the second database to create a comparative profile report, the processor maintaining a matrix of counts for every category of every variable for both the first and the second databases, so that the process of creating a comparative profile report is passed through the first database, wherein how often the process of creating the comparative profile report is passed through the first database is not determined by how many predictor variables are stored in the first and the second databases.
