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 to perform only specific operations related to their assigned tasks. For finergrained control, you can define realms around individual tables and authorize users to perform
certain operations on them, and also have a realm around the entire schema to protect the entire
application. Be aware, however, that this type of configuration may slow performance, but it does
enable you to grant realm authorization to some of the objects in a schema.
