As you can see, factors can play a significant role in application logic codified in your PL/SQL programs and can be integrated into row-level security mechanisms such as Oracle VPD, Oracle OLS, Oracle FGA, and database views. The implementation of factors as PL/SQL opens up these possibilities and just about any PL/SQL-based database feature such as database triggers or database...

The users might also have access to execute PL/SQL procedures that are required to participate in the transactional nature of the system, especially in packaged applications for...

Note that technologies such as fine-grained OS access control lists, based on IEEE’s POSIX 1003 standards, would offer a solution that uses a non-root account as the file owner, but for brevity we simply used the root account.. With this file populated, we can now...
