DDD Reference: Patterns and Definitions

This document is meant as a convenient reference for those who know the principles of Domain-Driven Design (DDD). It does not contain full explanations of DDD or even of the terms and patterns covered. It is intended to be used as a complement to the books, training courses, and the other resources available to those learning about DDD.

The pattern summaries in this Reference are based on extracted summaries from the 2004 book (see below). In addition, Eric Evans has improved the descriptions of some of the patterns and added three patterns that didn't make it into the original book, which Eric now thinks of as part of his understanding of DDD.
