Explanation:
DDL and DML operations on realm-protected objects do not have a measurable effect on Oracle
Database.Oracle recommends that you create the realm around the entire schema, and then
authorize specific users toperform only specific operations related to their assigned tasks. For
finer-grained control, you can definerealms around individual tables and authorize users to
perform certain operations on them, and also have arealm around the entire schema to protect the
entire application. Be aware, however, that this type ofconfiguration may slow performance, but it
does enable you to grant realm authorization to some of the objectsin a schema.
The performance overhead of Realms is between 3 and 5 percent.
