I personally think databases are WAAAAY overused. For a lot of projects, 
some sort of Ada persistent storage is a better solution. The problem in the 
past has been that such storage couldn't be abstracted very well, so one 
typically has built something custom. Ada 2012 has enough syntactic sugar 
that persistent storage libraries (like containers) should be reasonable to 
construct abstract systems that are still reasonably easy to read and write.

(The reason that we adopted the generalized reference feature that we did is 
because of the ability to use it to manage persistence -- in particular, to 
be able to figure out when the in-memory copy can be freed and written to 
the backing store.)
