[development] How do you create content for story by updating the database directly (what tables need to be updated?) instead of using the Drupal web application?

I have added two fields called latitude and longitude to the story content type. I then created content for story using the drupal web application and populating the Title, Body, latitude and longitude fields. How do you create content for story by updating the database directly (what tables need to be updated?) for the Title, Body, latitude and longitude fields instead of using the Drupal web application?
