MongoDB关系
拜托，你能说我，觉得我好还是坏？
我有两个对象，Exhibition 和 Stand。在我的逻辑中，Exhibition has_many Stands。 我想使用 mongodb。首先，我可以做嵌入展览的展台。但多个展览可以包含同一个展位。之后我认为，最好创建两个文档（集合）：Exhibition 和 Stand 并模仿关系引用。
1.Is it good idea?
如果这是个好主意，我会在展览文档字段stand_ids中创建，该字段将是数组，我将在该字段中推送必要的展位ID。
2.When i push ids in Exhibition and after this i
want to delete reference stand in Stands document.
How will be better to destroy id in Exhibition.stand_ids.
3.Think i by relational or it is good practice?
Please, can you say me, think i good or bad?
I have two objects, Exhibition and Stand. In my logic Exhibition has_many Stands.
I want to use mongodb. First, i can do Stand embedded in Exhibition. But several exhibitions can include same stand. After this i think, that will be better to create two documents(collections): Exhibition and Stand and imitate relation references.
1.Is it good idea?
If it is good idea, than i create in Exhibition document field stand_ids, which will be array and i will push in this field necessary stand ids.
2.When i push ids in Exhibition and after this i
want to delete reference stand in Stands document.
How will be better to destroy id in Exhibition.stand_ids.
3.Think i by relational or it is good practice?

如果您正在处理关系，则应该使用关系数据库。如果您的数据具有结构，那么使用 noSQL 解决方案就没有意义。
我给您的建议是使用最适合该工作的工具。您尝试做的事情似乎对于关系数据库来说是理想的。
If you're working with relations you should use a relational DB. It doesn't make sense to use a noSQL solution if your data has structure.
My advice to you would be to use the tool most suited for the job. What you're trying to do seems to be ideal for a relational DB.
在每个类中使用上述关系。
use above relationship in each of the class.
