# user database

sqlite (preferred)

in the spirit of minimalism, the recommended database technology to use here is sqlite. sqlite databases exist as a single, atomic file, and are a good use for light applications, with low to medium concurrent loads.
it also allows for greater flexibility, and segregation for your application's data: you can create as many sqlite databases as you need.

optional
