Name VARCHAR(50),
DeptID INT, -- Foreign key on the "many" side
FOREIGN KEY (DeptID) REFERENCES Departments(DeptID)
);
* Eachdepartmentcan havemany employees# DeptID is aforeign keyin Employees.
Why Other Options Are Incorrect:
* Option A (Reflexive relationship) (Incorrect):Refers tounary (self-referential) relationships, not 1:
M relationships.
* Option B (Binary relationship) (Incorrect):A binary relationship involvestwo entities, but does not define where the foreign key is stored.
* Option C (Weak entity) (Incorrect):Weak entitiesdepend on a strong entity, but not all "many" sides are weak entities.
Thus, the correct answer isForeign key, as it is placed on the "many" side of the relationship.

NEW QUESTION # 31

* Orders is astrong entity(has OrderID as its own primary key).
* OrderDetails is aweak entity(depends on OrderID for uniqueness).
Why Other Options Are Incorrect:
* Option A (Association) (Incorrect):Associations describerelationshipsbut do not define strong/weak entities.
* Option C (Foreign key) (Incorrect):Weak entitiesdepend on foreign keys, butprimary keysdefine their status.
* Option D (Cardinality) (Incorrect):Cardinality definesrelationship constraintsbut doesnot differentiate entity types.
