Abstract:
A computer-based method of evaluating data in a general purpose computing facility, comprising the steps of:a) constructing a cross-tabulation of data from one or more databases; b) ascertaining from an end-user a first set of filter expressions to be applied to said cross-tabulation of data; c) evaluating said cross-tabulation of data using said first set of filter expressions to obtain results and storing said results of said evaluations in a status table, such that said status table contains, for each row of said cross-tabulation and for each column of said cross-tabulation, a True indication where all elements of said row or said column evaluate to True values, and otherwise a False indication; d) ascertaining from an end-user a second set of filter expressions, selected from said first set of filter expressions, to be used in creating a reduced view of said cross-tabulation of data; e) using said second set of filter expressions and said status table to determine rows and columns to be reduced in a view of said cross-tabulation of data, and to complete a reduced view; and f) presenting an end-user with said reduced view.
