title: Publish SQL tables to CKAN
body: <p>I am new in publishing data to CKAN and I want to ask if it is possible to publish some tables from an external database to CKAN.</p>
  <p>I managed to have a CKAN instance with the datastore extension up and running but I haven't figured out yet if I need to have the data saved in the datastore or if I can connect my external DB to CKAN directly.</p>
  <p>If I must use the datastore extension how can I connect it with my data?</p>
