How is the union transformation active transformattion

         Active Transformation: the transformation that change the no. of   rows in the Target.
            Source (100 rows) ---> Active Transformation ---> Target (< or > 100 rows)Passive Transformation: the transformation that does not change the
            no. of rows in the Target.
            Source (100 rows) ---> Passive Transformation ---> Target (100 rows)
            Union Transformation: in Union Transformation we may combine the  data from two (or) more sources. Assume Table-1 contains '10' rows   and Table-2 contains '20' rows. If we combine the rows of Table-1  and Table-2 we will get a total of '30' rows in the Target. So it is  definetly an Active Transformation.
