Hi all,

i'm an italian master student in Information Technology and i'm working on Oracle 8:
i'm modeling with Unified Modeling Language (UML) a new object-relational database
which represents a generic telecommunication network.

I have three questions about a new UDT definition:

  1. could i create a new OBJECT TYPE with an attribute VARRAY of REF?
  2. an attribute REF could point to a generic undefined object (like NULL) and could be 'casted' after?
  3. what's the scope of a new object defined as component of another object?

Thanks in advance,
Claudio.
