RE: Separation of Objects from Logic 2004-12-13 - By Aaron Seet
Martin Fowler calls #1 an "Active Record" and #2 a "Row Data Gateway" +
"Data Transfer Object" in his book "Patterns of Enterprise Application
Architecture"
http://www.amazon.com/exec/obidos/tg/detail/-/0321127420
It is a very decent book bringing murky ideas you had in mind about
application patterns into concrete forms. He has written alot that i cannot
duplicate, so i recommend you pick up this book.

1. Where each object is responsible for loading and saving it's data so has
both methods and properties. Intelligent objects one might say.
2. Where each object is just a class with properties, light weight, but
completely dumb. All logic is performed through a separate Business Logic
Layer.
