1. A method for generating a compressed product definition, the method comprising: receiving at one or more computers a product definition that includes two or more binary vectors, the vectors including at least one feature family having one or more product features, and the product definition being stored in a computer storage medium associated with the one or more computers; identifying two or more vectors that are different by one feature family; and generating a compressed product definition by using a Boolean logic operation to combine the feature family from the two or more identified vectors that is found to be different and preserving the product features included in the feature families of the two or more identified vectors that does have commonality.
