Substep 3.2. Absorbing lower degree relationship into a higher degree relationship
This step is to identify the inconsistent degree level of two identical entities in
different schemas A and B. The schema with the higher degree naturally dominates
the schema with the lower degree to ensure that there is no information loss after
transformation. This translation process is to absorb the schema with the lower de-
gree relationship by the schema with the higher degree relationship (Fig. 7.14 ).
