Oracle Internet Directory
Oracle Internet Directory is a native LDAPv3 directory service built on the Oracle
database that centralizes a wide variety of information, including e-mail addresses,
telephone numbers, passwords, security certificates, and configuration data for
many types of networked devices. You can look up enterprise-wide queuing
information—queues, subscriptions, and events—from one location, the Oracle
Internet Directory. Refer to the Oracle Internet Directory Administrator’s Guide for
more information.

The message format transformation feature supports applications that use data in
different formats. A transformation defines a mapping from one Oracle data type to
another. The transformation is represented by a SQL function that takes the source
data type as input and returns an object of the target data type.
