Case Study: Raiffeisen Bank achieves a single customer view, duplicate prevention and GDPR compliance with Ataccama ONE MDM

Raiffeisen Bank - Customer Case Study

Raiffeisen Bank engaged Ataccama to consolidate customer portfolios after multiple acquisitions, prevent duplicate client records, and prepare a unified customer base for cross‑selling. After an initial tactical consolidation, the bank expanded the engagement into a full‑scale master data management initiative using Ataccama ONE MDM to handle customer matching more consistently across the organization.

Ataccama delivered an MDM hub running in batch and online modes that consolidated data from four source systems daily, built a 3.2 million‑record master customer repository, processed 2 million records in batch each day, and supported about 30,000 API calls per day. The Ataccama ONE MDM implementation enabled real‑time duplicate prevention and fraud detection, GDPR compliance, KYC support, five web services for online data cleansing/validation, and duplicate reporting workflows—resulting in reliable duplicate prevention, improved client experience, lower costs, and more efficient marketing.
