DBV factors can also be configured to allow for the identity of a factor to be validated with a callout to a PL/SQL routine This PL/SQL routine will be called whenever the function DVSYS GET_FACTOR is called, the DVFF$ factor function is called, or the DVSYSSET_FACTOR function is called With this mechanism, we could establish a trust but verify model whereby DBV can verify that the identity is correct with respect to our own rules In our example, the factor assignment may be authorized but we might also have a requirement to validate the end user value set against a table that contains user names If the identity fails validation, it will be set to NULL so that other areas of DBV policy, such as subsequent use of the DBV factor in a DBV rule
