The brainiacs over at google have invented a novel hybrid data base for
their Ads business http://research.google.com/pubs/pub38125.html. It
supports hierarchical schemas.
Quote "With F1, we have built a novel hybrid system that combines the
scalability, fault tolerance, transparent sharding, and cost benefits so
far available only in “NoSQL” systems with the usability, familiarity,
and transactional guarantees expected from an RDBMS."

You are correct, it IS not and SHOULD never be used as a transnational
database. It is however, a great (read better, more natural, more scalable,
etc.) replacement to warehoses with star schemas and the like.
Conceptually, navigating MongoDB is similar to navigating IMS and IDMS and is
totally different then using relational sets (using SQL)
