Them??™s the Basics!
Believe it or not, in just one chapter, we??™ve introduced you to Active Record and walked you
completely through installing and configuration; plus, we??™ve built and explained complete
working programs showing the basic CRUD operations. It really is amazing how little you need
to do to get started with Active Record!
Of course, there??™s a lot more to Active Record than just the basics we??™ve covered here
(otherwise, this would be a very short book!).
