I know I am a little late.
From my experience with Oracle Database:

ORACLE MYSQL(equivalent)
-------------------------------------------------------------------
DATABASE MYSQL INSTALLATION
SCHEMA DATABASE

So in Oracle a Database is an instance running on an Oracle installation,
While with MySQL you need different installations to have different instances(mysqld).
In my opinion Oracle naming approach is more correct, if you consider a Database as a RDBMS, anyway, MYSQL IS GREAT!

Aloha!

In your two examples:

SELECT * FROM server.sales.schema.product;
SELECT * FROM server.product.schema.product;

I'm a bit tired, so maybe I'm not seeing it, but what goes in the schema
place holder?
