Betreff:	Object Role Modelling (ORM) or UML or ?? for designing Schemas


I would like to hear, which modelling languages and/or methods you use when 
developing Schemas.
In an article "Object Role Modelling and XML-Schema" was written that the 
data modeling support is richer than other notations, i.e. UML.
My first thought is, that it has more advantages to stick to a widely used 
modelling language like UML particularly as the ORM-Diagram is quite 
confusing when complex relations are expressed.

But the approaches of UDDI and the Specification from Rational seems to be 
For example, elements of one complexTpye are displayed in Rational 
specification as role-names and  in UDDI they are either attributes 
(simple) or other classes which are
linked with an association.

I would be glad, to hear from best practices, experiences and maybe other 
ressources about this topic.
Thank you!!
