As functional_test said. Also note that this e.g. depends on how long lived your data is.

(An update routine can be run at any point with low use like Xmas, etc. This is potentially neat, depending on use statistics.)

I'm not saying this is a common thing, but the lack of joins makes the data a bit more flexible -- this can't be too much, if nothing else because then the Javascript will begin to break.

(I do think there are much more use cases for nosql than as a Memcached with more features. Where an old job used MongoDB wasn't one.)
