I was able to access the derived views from db-A database and make use of it in the db-B by adding the database name in the prefix of the view.
For instance, you could add the database name in the **prefix with dot (.)** as follows,
> Select * from db-A.<view_name_from_db-A>
Also, when performing operations like Union, Join, I was able to directly access the views from db-A in db-B without adding the database name in the prefix.
Hope this helps!
