I ran across this article today clarifying when using a document store (eg MongoDB) is a good idea, and when it's not, compared to a traditional database (eg PostgreSQL).
It makes a lot of sense actually, since it's hard to relate disparate documents together without database support for the relations. But the article, being from 2013, is pretty old now.
Do these arguments still hold up today?
@cuchaz fun fact: PostgreSQL is also a document store.
