Sending messages between objects and the observer pattern?

[lucky6969b]

Are they somehow related to each other?

Everything is related to everything else in some way.

Is the observer pattern a "wrapper" or say I don't know different ways of presenting the messaging system?
Thanks

I don't quite understand what you're asking but in my view the design pattern that's closest to a message system is Mediator. It's a complexity reducing pattern and the idea is to broadcast messages among anonymous objects rather than letting them communicate directly knowing about each other.

Regarding Observer I'd say the notification part can be though of as messaging. And in the GoF book a variation of Observer is described which uses a Mediator for more complex notification needs.
