Answer to Question 1

In SQL, relationships are created using a FOREIGN KEY constraint. This has the format:

CONSTRAINT ConstraintNameFK FOREIGN KEY(ForeignKeyColumnInC urrentTable REFERENCES ReferencedTableName(PrimaryKeyColumnInR eferencedTable)

The constraint thus names the foreign key column in the current table and its corresponding primary key in a referenced table. As an example, consider an advising relationship from STUDENT to FACULTY. The following constraint might appear in the SQL statement creating the STUDENT table:

CONSTRAINT AdvisorFK FOREIGN KEY (AdvisorID) REFERENCES
FACULTY (FacultyID)

Answer to Question 2

TRUE
