What are the advantages of Oracle Virtual Directory?

Oracle Virtual Directory minimizes or eliminates the need to change existing infrastructure or applications when you add new ones, saving the time and expense.

Data translation and joining capabilities allow you to create an integrated view of multiple data sources without changing their structure. This enables organizations to share the data that resides in their own repository while retaining full control of it and monitoring its usage. The sources can be separately owned and need not be synchronized. Users see only a single, logical LDAP tree, although there may be multiple data sources.
