Teradata says its CRM technology will help the bank deliver highly-targeted and event-triggered marketing campaigns, supported by its enterprise data warehouse - a centralised, continuously-updated repository of integrated, detailed transactional and customer data.

Event-triggered marketing is made possible through the creation of business rules within the Teradata CRM software that are automatically deployed within the data warehouse. This enables Barclays to identify and alert staff to significant changes in customer behaviour.

Chris Armitage, vice president, Teradata UK and Ireland, says: "Teradata CRM will help marketing users derive ever-greater business value from the volumes of fresh customer information streaming into Barclays' Teradata Warehouse, allowing marketers to rapidly identify and act upon new revenue-generating opportunities."

The vendor says the implementation follows proof-of-concept testing which showed that the reuse of enterprise customer data resulted in more business value and return on investment from Barclays' data warehouse.

In 2004 the bank consolidated its disparate databases across the enterprise onto a single platform supplied by Teradata.
