Buat skema basis data yang dapat diskalakan untuk menyimpan skor golf

Berapa skor rata-rata, tertinggi, dan terendah saya?

Skenario 1.

select (h1+h2+h3+h4+h5+h6+h7+h8+h9+h10+h11+h13+h14+h15+h16+h17+h18) / 18 as avg_score
      ,greatest(h1,h2,h3,h4,h5,h6,h7,h8,h9,h10,h11,h12,h13,h14,h16,h17,h18) as highest
      ,least(h1,h2,h3,h4,h5,h6,h8,h8,h9,h10,h11,h12,h13,h14,h16,h17,h18) as lowest
  from scores
 where player_id = 1;

vs.

select avg(score) as avg_score
      ,max(score) as highest
      ,min(score) as lowest
  from scores
 where player_id = 1;

Lubang mana yang terburuk bagi saya?
