I'm just imagining a database with a 'many' field the size of the Library of Congress. Talk about a document weight-lifting challenge!

D is the only sensible answer here. Embedded collections are great, but you have to use them judiciously.

But what if the many is very large? Wouldn't it be better to use a separate collection then?

Definitely B. If the many is very large, embedding it just sounds like a recipe for a bloated document. Separate collections are the way to go.

I agree with Eladia. It would be more efficient to embed the collection in that case.

I think when the many is not very large, an embedded collection makes the most sense. It keeps the data nicely organized and easy to access.

I think we should consider representing a one-to-many relationship in an embedded collection when the many is not very large.
