   • Present Information
     • Presenting Information is important, because if you have the database user friendly, anyone could delete another person's form and nobody would be able to get it back.. The forms and reports must not be user friendly, so that these things don't happen and it's laid out much better for people to understand.
   • Improve Productivity
