Doctrine ORM and tactical DDD concepts

This tutorial will introduce you to using Doctrine ORM together with tactical DDD concepts.

Our approximate plan of operation:

1. Installation and hoping that it will go smoothly :-)
2. Getting started with a simplistic "already known" Authentication domain, without ORM
3. Discussion of the first implementations popping up
4. Introducing some DDD concepts:
   • Domain and Infrastructure
   • Value Object
   • Aggregate Root
   • Entity
   • Repository
   • Read Model
5. Looking at how to improve our Authentication code
6. Wiring the ORM into our Authentication code
7. Exploration and discussion of a new domain, one of either:
   • Blog Post
   • Hotel Booking

Installation

First, install composer.

After that, you can run:

composer install
