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.)
