ABSTRACT:
Methods and system for comparing tables of a database are set forth. Within each table are multiple rows, each row having multiple columns, each column having a datum contained therein. The methods include retrieving the datum from within each column of each row of each table, and determining a value for each row based upon the datum contained within the columns thereof. For each table, the values of the multiple rows are combined using a commutative function to produce a separate table result for each table. The table results are then compared to determine the probability of equality of the at least two tables.
