Hi every body, i really need to understand and get the answer for this question, can any one help me PLEASE??


In database design world, it is so common to find binary relationships of type 1:M. How is this implemented when relational schema is translated into relational data model? Also, it is often possible to find M:N relationships; for example as they occur between Orders and Items. In this scenario, is it possible to successfully map a binary M:N relationship type without requiring a new relation? Why or why not?
