Hey Guys,

I started that one hour proof of concept with this in mind. Doctrine is 
split into DBAL and Doctrine ORM. What I integrated into the 
DatabaseConnection was Doctrine DBAl. So basicly nothing changes to the 
outside. Everyone can still use SQL like they're used to. But 
Extbase/Flow ORM can use Doctrine ORM on top of that, and also here the 
changes aren't that big.

So this strategy enforces incremental refactoring and improvement in a 
way that newly built/rebuilt components can use ORM and older ones still 
SQL. The cost of this becomes much smaller.

Sounds like a solid roadmap to me, do you agree?

Greetings,

Tom
