A method of correlating data for multiple product configurations is provided comprising enhancing, by a processor, data set definition to accommodate data models of data sets describing multiple product configurations. The method also comprises comparing, by the processor, values of the data sets utilizing at least one matching algorithm and effectivity expressions identifying relevant rows for comparison in the data sets. The method also comprises enhancing, by the processor, the at least one matching algorithm to identify perfect and partial matches between the data sets wherein values of all data contained in the data sets are compared in one single operation comprising simultaneous validation of engineering data for the multiple product configurations.
