Abstract

A generalized data set comparison is performed which identifies "logical matching" in datasets which may not "physically match". Control statements are utilized by which the algorithms for what constitutes a logical match can be defined. Ignoring the expected differences allows focus on unknown differences, or confirmation of a logical match between records. A comparison of the net differences between two files can be achieved by ignoring or bypassing expected differences, where these expected differences are: o Predictable o Can be qualified and described by control statements
