Next-Generation Data Warehouse (DWH) Implementation

Query times –70%

Challenge

The bank's legacy data warehouse could no longer handle growing transaction volumes or support complex analytics. High-latency data pipelines delayed reporting, banking systems, CRM, and digital channels remained disconnected, compliance gaps existed against GDPR and local data protection laws, and the bank had no way to support real-time dashboards or predictive analytics.
