Object Relational What?

Object Relational What?

How does Doctrine talk to your database? What are Unit Of Work, Identity Map and Proxy? These are the questions I want to answer in this talk. We will look at how Doctrine ORM implements these patterns, why and most importantly why you should care about this.

Have you ever wondered why Doctrine makes queries when you didn’t expect it? Did you encounter a “A new entity was found through the relationship”-error and just randomly tried things until it works? You are not alone! Let’s look behind the curtains of Doctrine and figure these things out.
