Case Study: One of the Largest Telecommunications Companies in the USA achieves faster, actionable customer insights with HCL's next-gen data platform

HCL Helps Implement Next-Gen Data Platform For Improved Customer Insights

The client, one of the largest telecommunications companies in the USA, was struggling with rapidly growing new‑subscriber and historical data and needed an agile platform to generate actionable customer insight for better targeting and acquisition. Their Teradata-based Enterprise Data Warehouse could not scale or process unstructured and semi-structured sources (clickstream, social) fast enough, so they engaged HCL to modernize their analytics platform.

HCL implemented a next‑gen Integrated Data Warehouse combining a Hadoop data lake with the existing Teradata EDW, a Denodo semantic layer for data virtualization, HCL’s DMF for high‑velocity real‑time ingestion, reusable transformation libraries, and sandbox environments for advanced analytics. The HCL solution delivered seamless data delivery and a hybrid BI architecture that preserved prior BI investments while enabling analytics for new sources in hours instead of months or years, improving time‑to‑insight and customer targeting.
