ZPatterns is very much about objects and collaborations between objects.

The Coad notation is very good for talking about objects like this.

TransWarp is more about classes, and generating customized classes from 
a mixture of existing classes and aspects. You can understand aspects as 
declarations about how to handle certain kinds of behaviour.

UML is very good for talking about classes and the relationships that 
can exist between objects of particular classes.



Often, I tend to think in Coad, but write in UML.
