How does a commercial database system such as Oracle support distributed databases?
Oracle fully supports distributed computing. A really good overview of this topic is provided in the Oracle Concepts document and I'd suggest that you start there for a detailed set of information. There's really too much on the subject as a whole to lay it all out here. But in general, Oracle provides basically transparent access for users to multiple databases particularly via the use of database links. A user from database A can access data from database B easily. For example: SELECT * FROM emp@databaseB; This query is accessing the emp table located on database B. You can create a synonym for emp@databaseB so that the user could simply enter "SELECT * FROM emp" and it would go to databaseB.
So... Oracle does fully support distributed database computing and a wealth of info on that subject awaits you in the Oracle Concepts guide!
