The existing ORMTable functionality I wrote is intended as a very simple
and lightweight layer on top of the regular database abstraction MediaWiki
has. It is not a fully fledged ORM framework and is not intended to be
I think it's a very bad idea to try to turn it into one. If you really
something more like a full object relational mapper, then you'll be better
of starting from scratch after putting some serious thought into how
going to do it. I do suspect that most core developers (including me) will
be rather sceptical of putting such a thing into core though, as it would
seriously impact a lot of existing code.
Many frameworks allow to combine "direct" SQL calls and ORM calls, so
there is not that big legacy compatibility problem.
The efficiency could be a problem, though. Not all of ORM's are
heavy-weight. For example, Yii's is quite light however queries weren't
always most efficient. I used to work with Yii recently, that's why I
asked. Speaking of Java, that's more heavy-weight, something like Doctrine,
probably (which I didn't use yet).
