* Duplicate information in parent and child tables

I have a parent table and a child table. In order to detect duplicate
information I need to consider both tables. This means that a "duplicate
record" consists of one parent record and one or more child records.
Is there any standard approach to solve this issue?
Respectfully,
Jorge Maldonado
