Many-to-Many Relationships

A many-to-many relationship allows you to define connections between the records of any two tables, by specifying the relationship type other than “one-to-one.”

A many-to-many table is a table describing how two tables are linked with each other.

For example, the User and the Group tables may contain many records with users and groups, accordingly. A user may be in more than one group, and a group may include many users, so, in this case, these two tables are bound as shown below:
