Правильно ли связал таблицы (Один к многим)?

CREATE TABLE Conferences(
ConferenceID INT NOT NULL ,
ConferenceName nvarchar(10) NOT NULL,
 
PRIMARY KEY (ConferenceID)
)

CREATE TABLE Divisions(
DivisionID INT NOT NULL,
DivisionName nvarchar(15) NOT NULL,
ConferenceID INT
 
PRIMARY KEY (DivisionID)
)

INSERT INTO Conferences(ConferenceID, ConferenceName) VALUES(1, 'Eastern')
INSERT INTO Conferences(ConferenceID, ConferenceName) VALUES(2, 'Western')
 
INSERT INTO Divisions(DivisionID, DivisionName) VALUES(1, 'Atlantic')
INSERT INTO Divisions(DivisionID, DivisionName) VALUES(2, 'Central')
INSERT INTO Divisions(DivisionID, DivisionName) VALUES(3, 'Southeast')
INSERT INTO Divisions(DivisionID, DivisionName ) VALUES(4, 'Northwest')
INSERT INTO Divisions(DivisionID, DivisionName ) VALUES(5, 'Pacific')
INSERT INTO Divisions(DivisionID, DivisionName ) VALUES(6, 'Southeast')

ALTER TABLE Divisions
ADD FOREIGN KEY(ConferenceID) REFERENCES Conferences (ConferenceID)

UPDATE Divisions
SET ConferenceID=1
WHERE DivisionID IN (1, 2)

CREATE TABLE Conferences(
    ConferenceID INT NOT NULL IDENTITY,
    ConferenceName nvarchar(10) NOT NULL,
 
    PRIMARY KEY (ConferenceID)
)
 
CREATE TABLE Divisions(
    DivisionID INT NOT NULL IDENTITY,
    DivisionName nvarchar(15) NOT NULL,
    ConferenceID INT NOT NULL
 
    PRIMARY KEY (DivisionID)
)

ALTER TABLE Divisions
ADD FOREIGN KEY(ConferenceID) REFERENCES Conferences (ConferenceID)
