Suppose you maintain profile data both in a SQL database and an LDAP directory. ATG’s profile repository ships with a user composite item descriptor comprised of just one primary item descriptor and no contributing item descriptors. The primary item descriptor is the user item descriptor. You can add to the composite item descriptor the user item descriptor from the LDAP repository as a contributing item descriptor. If there are any property name collisions between the SQL repository and the LDAP repository, you can resolve them by mapping the properties explicitly to different names in the composite repository configuration. Once you’ve done this, your ATG applications can view both LDAP profile information and SQL database profile information as properties of composite items in the composite user item descriptor.
