Development/Testing/Production

• Rails assumes and automatically sets up multiple
  database connections for the various stages of
  development
• It assumes databases exist for development,
  testing, and production i.e. ltprojgt_development
• If the user would like to modify the name of the
  database, they can simply change it in the
  database.yaml file automatically created with
  each project
