In this module, we've discussed the advantages of using Active Record and using association macros. Active Record automates the ORM setup significantly in a simpler format.

We also discussed:

• The features of Rake
• Common methods accessible through Active Record associations
• How to use association macros

With this understanding of Active Record, persisting data becomes easier. We can now set up and work with models and build associations between them by leveraging methods such as belongs_to, has_many, and has_many :through. We're well on our way to being able to build fully functioning apps end-to-end.
