Question

想要一些意见是最佳方式。

因此，我正在为比赛创建一个系统，类似于足球/足球等体育运动的方式等。

目前我有一个赛季，一个赛季然后有很多球队，一个球队可以有很多会员。

一个赛季有很多比赛，其中所有队伍将始终参加每场比赛，但并非所有队员都参加比赛。

存储团队成员参加比赛的最佳方式是什么？

目前我只考虑比赛表和成员之间的一个支点，但是这并不表示该成员属于哪个团队，而成员可以属于许多团队。你有3路数据透视表吗？

继承我当前的表结构

Answer 1

我会有一个players表格，以便玩家的信息与任何团队信息分开。那么你可能有一个competition_players表或类似表，它有三个外键：团队ID，玩家ID和竞争ID，所以你可以看到谁在每场比赛中为哪支球队效力。
