MongoDB數據庫關係

Question

我剛剛開始在MongoDB中構建數據庫。我有2張桌子，球隊和賽程，並且每個Fixture文件應該有2個鏈接到Fixtures表，一個HomeTeamId和一個AwayTeamId。這是做到這一點的正確方法嗎？

團隊：

{ 
    "_id": { 
     "$oid": "542978c4e4b0e67da1edc7f3" 
    }, 
    "TeamName": "Arsenal", 
    "BadgeSmall": "http://footballcomps.azurewebsites.net/Content/Images/Badges/Small/arsenal.png", 
    "BadgeLarge": "http://footballcomps.azurewebsites.net/Content/Images/Badges/Large/arsenal.png", 
    "TeamImage": "http://footballcomps.azurewebsites.net/Content/Images/Teams/arsenal.png", 
    "Formation": "http://footballcomps.azurewebsites.net/Content/Images/Formations/arsenal.png" 
} 

{ 
    "_id": { 
     "$oid": "542979c3e4b0e67da1edc807" 
    }, 
    "TeamName": "Aston Villa", 
    "BadgeSmall": "http://footballcomps.azurewebsites.net/Content/Images/Badges/Small/astonvilla.png", 
    "BadgeLarge": "http://footballcomps.azurewebsites.net/Content/Images/Badges/Large/astonvilla.png", 
    "TeamImage": "http://footballcomps.azurewebsites.net/Content/Images/Teams/astonvilla.png", 
    "Formation": "http://footballcomps.azurewebsites.net/Content/Images/Formations/astonvilla.png" 
} 

{ 
    "_id": { 
     "$oid": "542c45eee4b0413a3dd4d43e" 
    }, 
    "TeamName": "Crystal Palace", 
    "BadgeSmall": "http://footballcomps.azurewebsites.net/Content/Images/Badges/Small/crystalpalace.png", 
    "BadgeLarge": "http://footballcomps.azurewebsites.net/Content/Images/Badges/Large/crystalpalace.png", 
    "TeamImage": "http://footballcomps.azurewebsites.net/Content/Images/Teams/crystalpalace.png", 
    "Formation": "http://footballcomps.azurewebsites.net/Content/Images/Formations/crystalpalace.png" 
}

    "HomeTeamScorers": "", 
    "AwayTeamScorers": "Ozil 33,Welbeck 34,Cissokho 35 (OG)" 
} 

主隊：阿森納，客場球隊：水晶宮：

我個人建議在遊戲中嵌入團隊對象團隊及其圖標在一個賽季內不太可能發生變化。撥打1個電話而不是3個。
