3 About UDR and ESPR

This introduction will familiarize you with the functionality, system architecture, and configuration of the Oracle Communications User Data Repository (UDR) platform.

This platform provides a highly-scalable, consolidated database back end for subscriber and profile data that can be leveraged across the product portfolio. UDR can utilize multiple application front ends with the database.

Currently, UDR supports the Oracle Communications Enhanced Subscriber Profile Repository (ESPR) application, a function used for the storage and management of subscriber policy control and pool data. XML-REST and XML-SOAP interfaces are used by ESPR for creating, retrieving, modifying, and deleting subscriber and pool data.
