> The truth is that relational databases scale up just fine when placed in the hands of people that (1) know what they are doing, (2) aren’t afraid to learn new things, and (3) don’t mind doing the work necessary
This is true FOR ANY KIND OF DATABASE.
In fact, a RDBMS is far easier to use because it TAKE CARE OF THE HARDEST THINGS OF COMPUTER DEVELOPMENT. Good luck for the average joe to understand ACID and try to implement it on top of Mongo.
RDBMS are for everyone NoSql are for Pros.
