<p>
There was SQL.

<p>
And it was okay.

<h2>And then...</h2>
<p>There was noSQL!</p>
<p>And it scaled and it was all javascripty and all the hipsters loved it and everyone was happy.

<h2>noDB</h2>
<p>So you want to add some persistence to your simple web app.</p>
</section>
<section>
<p>Okay so just require that each user have a couch installation.</p>
<p>Or make redis a dependency. Probably include some build scripts or something to make it easier since it's the only thing in the app that needs to be compiled.</p>
<img src="http://upload.wikimedia.org/wikipedia/commons/thumb/7/72/ER_Diagram_MMORPG.png/539px-ER_Diagram_MMORPG.png">
<p>Maybe it would be easier to build SQLite?</p>
