Mam tabelę z wieloma polami, które są kluczami obcymi do klucza podstawowego w innej tabeli. Na przykład :

Fixture Id (PK)
HomeTeamId (FK to Team.TeamId)
AwayTeamId (FK to Team.TeamId)
HomeTeamCoachId (FK to Coach.CoachId)
AwayTeamCoachId (FK to Coach.CoachId)

Czy lepiej byłoby oddzielić te dane na 2 tabele HomeTeam i AwayTeam z obcym kluczem do FixtureId? To właśnie zostało wygenerowane przez Entity Framework:

FixtureId PK
HomeTeamId int
AwayTeamId int
HomeTeamCoachId int
AwayTeamCoachId int
AwayTeam_TeamId FK
HomeTeam_TeamId FK
AwayTeamCoach_CoachId FK
HomeTeamCoach_CoachId FK

Zostało to wygenerowane przez tę klasę:

public partial class Fixture
{
    public int FixtureId { get; set; }

    //foreign key
    public int AwayTeamId { get; set; }
    //navigation properties
    public virtual Team AwayTeam { get; set; }

    //foreign key
    public int HomeTeamId { get; set; }
    //navigation properties
    public virtual Team HomeTeam { get; set; }

    //foreign key
    public int AwayCoachId { get; set; }
    //navigation properties
    public virtual Coach AwayCoach { get; set; }

    //foreign key
    public int HomeCoachId { get; set; }
    //navigation properties
    public virtual Coach HomeCoach { get; set; }
}

Czy ktoś może mi powiedzieć, czy jest to właściwy sposób, aby to zrobić?

EDIT: W odpowiedzi na Slauma

Więc moje zajęcia wyglądałyby tak po prostu? Czy konfiguracja w OnModelCreating oznacza, że ​​nie potrzebuję kodu związanego z kluczem obcym w mojej klasie urządzeń?

 protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        // Entity Type Configuration
        modelBuilder.Configurations.Add(new TeamConfiguration());
        modelBuilder.Configurations.Add(new CoachConfiguration());
        modelBuilder.Configurations.Add(new FixtureConfiguration());

        modelBuilder.Entity<Fixture>()
            .HasRequired(f => f.AwayTeam)
            .WithMany()
            .HasForeignKey(f => f.AwayTeamId)
            .WillCascadeOnDelete(false);

        modelBuilder.Entity<Fixture>()
            .HasRequired(f => f.HomeTeam)
            .WithMany()
            .HasForeignKey(f => f.HomeTeamId)
            .WillCascadeOnDelete(false);

        modelBuilder.Entity<Fixture>()
            .HasRequired(f => f.AwayCoach)
            .WithMany()
            .HasForeignKey(f => f.AwayCoachId)
            .WillCascadeOnDelete(false);

        modelBuilder.Entity<Fixture>()
            .HasRequired(f => f.HomeCoach)
            .WithMany()
            .HasForeignKey(f => f.HomeCoachId)
            .WillCascadeOnDelete(false);
    }

public partial class Fixture
{
    public int FixtureId { get; set; }
    public string Season { get; set; }
    public byte Week { get; set; }

    //foreign key
    public int AwayTeamId { get; set; }
    //navigation properties
    public virtual Team AwayTeam { get; set; }

    //foreign key
    public int HomeTeamId { get; set; }
    //navigation properties
    public virtual Team HomeTeam { get; set; }

    //foreign key
    public int AwayCoachId { get; set; }
    //navigation properties
    public virtual Coach AwayCoach { get; set; }

    //foreign key
    public int HomeCoachId { get; set; }
    //navigation properties
    public virtual Coach HomeCoach { get; set; }

    public byte AwayTeamScore { get; set; }
    public byte HomeTeamScore { get; set; }
}
