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.

C? Really? Embedding collections should be the exception, not the rule. What are they thinking?

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, separate collections are better for large amounts of data.

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.
