In part 4 we introduced some front end loveliness with Bootstrap. But now we get into the back end, specifically, connecting our Symfony 2 application to our Database.
We will be looking into Doctrine Object Relational Mapper (ORM).
As a beginner it can seem a little overwhelming having to learn a whole new way of interacting with your Database, AS WELL AS the concepts of MVC, and all the configuration, setup and more.
Hopefully this video goes some way towards demystifying what at first appears a very complicated way to do something you will likely already be familiar with - db interaction. But stick with it, as this stuff is well worth learning.
