Hi,
If you have configured correctly the ODBC connection to Denodo following the section [access to Denodo through ODBC](https://community.denodo.com/docs/html/browse/6.0/vdp/developer/access_through_odbc/access_through_odbc), you will be able to use elements from a database in another database.
For instance, a user connected to database DB1 will be able to use elements in database DB2 to create a new view in DB1, as long as she has the required privileges on DB1 and DB2.
To do that, what you should do to reference a view from a different database, the name of the view must be preceded with the name of the database the view belongs to: <database_name>.<view_name>.
Hope this helps!
