by fstender in Databases
New To NoSQL

I've been struggling on how to decide how to store these documents. I

MongoDB Schema Design - Many small documents or fewer large documents?
by Danny in Databases

I'm prototyping a conversion from our RDBMS database to MongoDB. While denormalizing, it seems as if I have two choices, one which leads to many (millions) of smaller documents or one which leads to fewer (hundreds of thousands) large documents.
