title: Ruby: CSV instead of database
body: <p>Is there a framework or gem or similar to use a CSV as a database? Like if I wanted to quickly run a few Ruby commands on a CSV is there something I can use to load it into the console and work directly on it then re-export as CSV all without an actual database?</p>
  
  <p>I know it'd be slow, etc, but it's not meant to run an app or anything, just run conversions on datasets, etc.</p>
  
  <p>I guess it could be loaded into memory as a huge hash then managed like that? Something along those lines? Or is there something better?</p>
