Client Overview
One of the largest U.S. regional banks, managing approximately $90B in assets and operating nearly 400 branches nationwide, faced increasing complexity following multiple mergers. Fragmented systems, rising regulatory scrutiny, and accelerating digital expectations created urgency to modernize its enterprise data ecosystem end-to-end, without compromising regulatory confidence or operational resilience.
Customer Challenge
Multiple mergers left the bank with three legacy warehouses and siloed data marts, creating inconsistent reporting, high reconciliation effort, and governance gaps across Risk and Finance functions.
Key issues:
Fragmented architecture and duplicated data
Limited lineage transparency increasing regulatory scrutiny
Manual, reconciliation-heavy reporting driving high costs
Redundant tooling and slow analytics delivery
What was at stake?
Without modernization, the bank faced rising regulatory exposure, escalating run costs, slower innovation, and reduced executive confidence in enterprise data.
Ness Solution
Ness led a multi-year, strategy-first modernization to implement a governed Enterprise Data Hub (EDH) using an Enhanced Medallion Architecture (EMA).
The transformation delivered:
Consolidation of three warehouses into Snowflake
Denodo virtualization for seamless migration
Embedded lineage, OCC-aligned governance, RBAC and ABAC security
Data-as-a-Product framework and enterprise data marketplace
Stabilized platform with tool rationalization
Governance was embedded by design, not added later.
Engagement model
The model ensured uninterrupted regulatory reporting while delivering incremental value.
