On the left is Oracle Internet Directory, which stores a change log and synchronization profiles. Arrows point from administrative changes and transaction-generated changes to Oracle Internet Directory. Oracle Internet Directory contains a change log and synchronization profiles for several connected third-party directories. An arrow points from the change log and synchronization profiles in Oracle Internet Directory to the Directory Synchronization Service. An arrow points from Oracle Human Resources to the synchronization agent for Oracle Human Resources. Another arrow points from the synchronization agent for Oracle Human Resources to the Directory Integration Service, illustrating the relationship via a tagged interface. Bidirectional arrows show the reciprocal relationship between Oracle Internet Directory and two connected third-party directories via LDAP interfaces.
