title: Database Structure for Geocoding
body: <p>I want to try and do a geocoding application and access data stored in a SQLite database. A postcode, town or city will be supplied, and I want to return the long/lat. I want it to be screaming fast but I'm unsure about how to organise the data in the DB.</p>
  
  <p>Here is the data im working with:</p>
  
  <blockquote>
    <p>Town, City, Postcode, Country, Longitude, Latitude</p>
  </blockquote>
  
  <p>This may be simple but im new to this, I would benefit from some advice.</p>
