> The situation is sufficiently untenable that it’s rare to write apps without making use of an ORM or some similar library, creating additional cognitive overhead to using a SQL database, and creating painful impedance mismatches. That's only true if you're using PHP,Python,Javascript or dynamically typed language. Mongo documents don't automatically map to classes in C++ or Java, the impedance mismatch still exists and a data mapper library is still required, just like with RDBMS.
