A many-to-many relationship is usually resolved by making a tertiary (third intermediate) table where PKs of both the related tables are recoreded as FKs.

Example: A student can take many classes and a class can have more than one student. This shows a many to many relationship.

To address this issue we have to create a third table in addition to the STUDENT and CLASS tables. This table will store the student id and class id.


tblSTUDENT                           tblCLASS                tblStudentClass
stdID                                       clsID                        stdID
stdName                                  clsName                  clsID
