Case Study: Resona Group achieves real-time customer insight and faster service with Teradata Active Data Warehouse

On the fast track towards advanced analytics and true customer insight with Teradata's Active Data Warehouse

The Resona Group, one of Japan’s largest retail banking groups (Resona Bank, Saitama Resona Bank and The Kinki Osaka Bank), serves customers through 14,000 employees, 2,200 ATMs, 230 call‑center reps and online channels. Facing intensified competition and the need for faster, more personalized service, Resona struggled with two separate systems (CRM and MCIF) that kept customer data siloed, slowed marketing development and could not efficiently handle peak loads of up to 200 transactions per second.

In 2013 Resona consolidated both systems onto Teradata’s Active Enterprise Data Warehouse, creating a Single View of the Customer and using hybrid storage and Teradata Active System Management to prioritize workloads and scale performance. The result was real‑time, high‑speed access for employees and customers, much faster marketing PDCA cycles, lower development and operating costs, improved event‑driven targeting and higher customer satisfaction—while positioning the bank to analyze growing volumes of mobile and multi‑structured data.
