Well associations are pretty fundamental to Active Record. You don't
have to use them but you'd just be creating a lot of work for yourself
and missing out on a lot of the handy bits in rails. rails.info is probably not a bad
place to start.

has_many / belongs_to is how you tell Rails that models are related...

Start reading here:

Look at the ActiveRecord::Base entry to begin your instruction Grasshopper...
