Case Study: Leading US Retailer achieves unified customer hub and real-time single view of 250M+ customers with HCL

A Leading US Retailer Consolidates Its Multiple Data Marts With HCL’s Expertise

A Leading US Retailer faced fragmented data across 30+ operational systems, Teradata overflow, and no golden customer record, and engaged HCL to consolidate its multiple data marts. HCL implemented real-time integration using IBM InfoSphere MDM and IIS, enabled real-time and batch de-duplication, automated stewardship rules, and prepared the environment for a single view of customers.

HCL migrated 250 million customer records from Teradata into IBM MDM and unified 30+ disparate data marts into a global customer hub, cleansing and de-duplicating 500 GB and handling over 2.5 TB of data. The HCL solution delivered real-time access to customer touchpoints, unified lifecycle visibility, and faster promotional roll-outs, providing measurable consolidation and improved data quality.
