Case Study: Kassenärztliche Bundesvereinigung (KBV) boosts query performance up to 20x and reduces energy costs by up to 75% with Oracle Engineered Systems

KBV Boosts Performance, Reduces TCO with Oracle Engineered Systems

Kassenärztliche Bundesvereinigung (KBV) is Germany’s national association for statutory health insurance physicians, representing more than 165,000 practitioners and analyzing healthcare data for the whole population. Faced with an outdated data warehouse that had to handle roughly 580 million treatment cases a year (about 200 billion records), KBV needed a high‑performance, flexible platform that would boost query speed (targeting ≥4x), integrate with its existing analytics tools, and avoid major changes to user interfaces.

KBV deployed Oracle Engineered Systems—including Exadata, Oracle Database with Real Application Clusters and Active Data Guard—delivering an 8x–20x increase in query performance, the ability to run several hundred complex queries per day and complete multi‑parameter analyses within 48 hours, and seamless integration with existing analytics. The solution cut energy consumption by ~75%, sped patching from days to minutes, kept interfaces unchanged to maximize user acceptance, centralized in‑house control, and met strict German data‑security standards (ISO 27001/27002).
