Re: Using fully qualified table_name.database_object in application code?

The best answer to your question is probably on Steve Adams' website - search for the word 'synonym'.

On high-concurrency systems with large numbers of users, the use of public synonyms leads to lots of overhead and contention handling negative dependency checking. (When I reference DUAL, I have to know that I don't own an object called DUAL that over-rides the public synonym called DUAL - so the library cache gets filled with lots of 'non-existent' objects of the same name - which adds to the length of time that it takes to search a chain for something that should exist).
