Rules can also be used to define database realms, which consist of a subset of the
schemas and roles that an administrator can administer. This ability is essential if an
organization uses its Oracle database to service multiple communities. You can
define a realm and give an administrator privileges on that realm without compromising
data in other schemas. The overall effect of realms is to allow secure
delegation of administrative responsibilities.
All of the rule enforcement is audited as part of the the Oracle Database Vault
Option, which provides the type of documentation required for complete compliance.
Figure 6-1 illustrates the various components of the Oracle Database Vault
Option solution.

Oracle Audit Vault Server
The Oracle Audit Vault Server was introduced in 2007 and collects data from audit
files in Oracle and in the underlying operating system. It consolidates this data in a
secure repository and provides out-of-the-box compliance reporting.
