One or two things to remember: if you aren't dealing with a huge
amount of data, and really just want to store it when you're done (or
periodically), and re-load it when you come back, Marshalling your
data to a file may be a better solution.

If you have data you want transactional file backed, but doesn't map
perfectly to relational models, you may want to try Pstore.

Relational Databases (SQL) are not the panacea of data storage, :)
remember your other options!
