For each m:n relationship type R, we make a new table (say S) to represent R. We also contain the primary key attributes of both the participating entity types as a foreign key attribute in S. Any easy attributes of the m:n relationship type (or easy components of a composite attribute) is also contain as attributes of S.
For example, the m: n relationship taught-by among entities COURSE and FACULTY should be shown as a new table. The structure of the table will contain primary key of COURSE and primary key of FACULTY entities
A new table TAUGHT-BY will be created as: Primary key of TAUGHT-By table
ID
Course_ID
{Primary key of FACULTY table}
{Primary key of COURSE table}
