In a one-to-many binary relationship, the primary key from the "many side" of the relationship is inserted as a foreign key in the "one side" of the relationship. It is a false statement.

Explanation:

Two entities participate in a binary relationship. Two relations together represent a one-to-many binary relationship. In this case the first key of the relation on one side of the relationship is inserted as a foreign key into the relation on many side of the relationship.

In one-to-many relationship, a record in a specific table can be co-related with one or more records in different table.

The foreign key can be used to store one-to-one binary relationship in the social database.
