I’m not talking about how much money you have, but all of the other things – receipts, drivers license, club cards, gym memberships, packs of sugar, …?

Well, this post is all about what’s stuck in your development environment. Perhaps one

This is a great feature because it allows you the option to create richer domain models and avoid the anemic domain model anti-pattern, which was coined by Martin Fowler and discussed at great lengths in Eric Evans’ book Domain Driven Design.

Unfortunately, this AspectJ-based solution discussed by Chris Richardson will not
