Vue + Firestore将userGroup分配给Article，将User分配给UserGroup

Question

不确定从哪里开始（我四处寻找帮助）。甚至不确定我是否要问正确的问题，因为在这种情况下我找不到任何文档或教程。我发现并开始使用Firebase firestore进行登录/身份验证，但组>用户>内容上没有任何内容。也许我搜索的字词错误。

我想用Firebase（Firestore）在Vue中构建一个应用程序。我希望不同的公司注册并创建用户帐户，一旦他们注册，就可以CRUD他们创建的文章。

我的问题：

1）Firestore的这种结构是否足够平坦？还是有更好的方法？

Companies:
 - Company-1 > Can access Articles 1, 4 & 7
 - Company-2 > Can access Articles 6 & 9
 - Company-3 > Can access Articles 2, 3, 5 & 8


Users:
 - User-1 > Belongs to Company-1 (access Articles 1, 4 & 7)
 - User-2 > Belongs to Company-1 (access Articles 1, 4 & 7)
 - User-3 > Belongs to Company-1 (access Articles 1, 4 & 7)
 - User-4 > Belongs to Company-2 (access Articles 6 & 9)
 - User-5 > Belongs to Company-3 (access Articles 1, 4 & 7)
 - User-6 > Belongs to Company-1 (access Articles 1, 4 & 7)


Articles:
 - Article 1
 - Article 2
 - Article 3
 - Article 4
 - Article 5
 - Article 6
 - Article 7
 - Article 8
 - Article 9

      "articleID_4": {

      "articleID_5": {
         "atricleContent": "here..."
      },
      "articleID_6": {
         "atricleContent": "here..."
      },
      "articleID_7": {
         "atricleContent": "here..."
      },
      "articleID_8": {
         "atricleContent": "here..."
      },
      "articleID_9": {
         "atricleContent": "here..."
      }

       }
    }

2）我可以使用Vue / Vuex或Cloud函数处理组/用户角色/权限吗？

如果您可以指出正确的方向；太棒了！
