2.The CDC stage takes two input data sets, denoted before and after, and outputs a single data set whose records represent the changes made to the before data set to obtain the after data set.However,Difference stage performs a record-by-record comparison of two input data sets, which are different versions of the same data set designated the before and after data sets.
