Case Study: Aetna achieves real-time, governed 360° employee and customer data integration with MarkLogic

Leading Health Insurer Uses MarkLogic‑based Operational Data Hub to Meet Changing Business Requirements

Aetna, a leading health insurer, needed a Human Resources Hub to consolidate employee data from acquisitions and hundreds of internal silos to achieve a 360-degree view of employees and support broader Customer 360 initiatives. The IT team faced costly point-to-point integrations, rigid relational database models that hindered incremental change, and the need for strong governance, auditability, traceability and agility to meet changing business requirements.

Aetna implemented a MarkLogic-based Operational Data Hub—covering data integration, an operational data warehouse, mainframe migration, Customer 360 and tiered storage—and delivered the line of business in nine months. The platform enabled real-time batch integration and search, data decoupling and reuse, canonical-model agility with ACID compliance, semantic enrichment of provider data, reduced hardware/software costs, and full data lineage and traceability.
