Oh, no! First of all, there is no general "nosql" feature set. There are
many nosql storages that totally focus on performance, but don't give lots
of features or schema/content structure abilities, these end up as simple
key-value stores.

But there are also others that really focus on giving you a better data
model than relational databases, while not so much focussing on special
in-memory performance etc. (having performance generally at the same level
as your typical RDBMS, however that also depends on the application and
how it uses the data storage, etc. pp.).

Especially JCR is at its heart about a more natural modeling and
unstructured data. Hence you get much more flexibility than with SQL
databases! RDBMS require you to change your schema every time you want to
add a new field, this is a big inflexibility.
