How to set up a base. Linking collections?

Question

MongoDB

For example, I have a product document:

{
   name: 'Cушилка"
   company: ['id231231313', 'id223234234']
}

Is it correct to write in the array all the id of the companies that sell this dryer? How then to request all these companies, sort them. And what if this dryer will be sold by 5,000 or 10,000 companies. How to deal with it?

Answer 1

On a side note:
It is better not to store in the product document something that is not very related to the product. It is better to put the links in a separate collection or write the product ID in the company's collection (which is also not very good).
