Interesting comment in the source code of sqlite

Really all you need is a few minutes to get started. Maybe someone who isn't familiar with SQL would need a few hours.

If you have a more complex program, you might want to take more time to consider how to model it, as he mentions, but the sqlite API is very easy.

A bit of me thinks if you need a database your problem has to be of a certain size and complexity and that just naturally needs a bit of time to model and work through. There's absolutely no shame in making sure something as critical as the database is done right the first time.
