婚姻關係

Question

需要一些意見，作爲這樣做的最佳方式。

所以我創建一個系統競爭，類似的方式運動，如足球/足球工作等

目前，我有一個賽季，隨後一個賽季有很多球隊，一支球隊可以再有很多議員。

然後一個賽季有很多比賽，其中所有的參賽隊都會參加每場比賽，但不是每個參賽隊都會參加比賽。

什麼是存儲團隊成員參加比賽的最佳方式？

目前我只想着比賽表和成員之間的一個關鍵點，但是這並不表示成員屬於哪個團隊，並且一個成員可以屬於很多團隊。你可以有一個3路數據透視表嗎？

Answer 1

我想有一個players表，使玩家的信息，從任何一支球隊的信息隔離。然後你可能會有一個competition_players表或類似的表，它有三個外鍵：團隊ID，玩家ID和競爭ID，所以你可以看到誰在每場比賽中爲什麼參加了比賽。
