BTW, DB2 doesn't have 'em either.
In DB2, you have Database -> Schema -> Objects
In DB2, you can of course have cross-schema queries but no cross-db
queries, unless you rig up the federated functionality to connect one
db to the other.
Much of the confusion stems from SQL-Server and Sybase having:
Database -> Objects
The Database is used to identify distinct schemas. I'm not sure if in
these systems they are physically separate entities (different lock
manager etc.)
