对象之间的Mongo DB关系 [英] Mongo DB relations between objects

问题描述

我正在尝试使用mongo db实现博客文章存储.

I'm trying to implement blog post storage using mongo db.

我有两个域实体:

博客文章"和作者"

当前，我已将AuthorId属性添加到博客文章实体.那是存储对象之间关系的正确方法吗?

Currently I've added AuthorId property to blog post entity. Is that the right approach to store relation between objects?

我会拒绝.您应该"以非规范化的方式将所需的一切存储在博客文档中(例如，博客文章，评论，标签等).因此，如果要显示作者的姓名，则应将其添加到博客文档中.这样就可以通过单个查询来获取整个页面的数据，这恰好是面向文档的数据库的重点.

I'd say no. You are "supposed" to store everything you need in a blog document in a denormalized way (e.g. the blog post, the comments, the tags, etc). So if you want to show the Author's name, you should add it to the blog document. This would allow to fetch an entire page's data with a single query, which is kinda the point of a document-oriented database.
