Unifying Retail Data at Scale: A Cloud-Native Data Modernization

A full-scale data modernization and migration, unifying fragmented enterprise data across SAP HANA, BigQuery, and multiple operational systems into a single Databricks-based data lake.

Client

A leading American discount closeout retailer.

Problem Statement

The client's data was fragmented across SAP HANA, BigQuery, and multiple enterprise tools, with no unified source of truth. This prevented real-time operational visibility, slowed analytics across regions, and created growing overhead as the business expanded its store footprint by 10% annually, making data modernization a priority for sustained growth.

Quick Summary

QBurst consolidated scattered enterprise data into a unified Databricks data lake, using internal accelerators to reduce the manual engineering effort typically required for large-scale data unification.

  • Unified previously fragmented data from SAP HANA, BigQuery, and enterprise tools into a single Databricks-based lake.
  • Digitized workflows reduced manual effort by 40%.
  • Architecture seamlessly supports 10% annual store growth across regional footprints.

Client Profile

Leading American discount closeout retailer offering deeply discounted, overstocked, and closeout products from name-brand and private-label suppliers. Experiencing rapid expansion and relying on a technology-driven retail model, the company focuses on operational efficiency, scalability, and personalized in-store experiences through data and digital transformation.

Fragmented Data and Scalability Constraints

Data scattered across disconnected systems limited the client's ability to see and act on operations in real time.

  • Data Fragmentation: SAP HANA, BigQuery, and multiple enterprise tools each held partial, disconnected views of operational data, with no single source of truth.
  • Manual Effort Overhead: Reconciling data across systems manually consumed significant operational effort across teams.
  • Scalability Pressure: Rapid expansion required a data architecture capable of scaling 10% annually without performance bottlenecks.
  • Limited Real-Time Insight: Lack of instant analytics, real-time alerts, and global search capabilities delayed operational decision-making.
  • Seasonal Load Variability: The business's seasonal nature created extreme fluctuations in system load that legacy infrastructure could not accommodate.

Data Modernization and Migration to a Unified Databricks Lake

We executed a full data migration and modernization initiative, consolidating the client's fragmented data landscape into a single Databricks-based data lake, using QBurst's internal accelerators to reduce the manual effort typically required to migrate and reconcile data at this scale.

  • Accelerated Data Unification: Used internal migration accelerators to extract, transform, and consolidate data from BigQuery and connected enterprise tools into a single Databricks data lake, reducing manual data engineering effort.
  • Unified Data Architecture: Structured the consolidated data within Databricks to serve as a single governed source of truth, replacing the fragmented, tool-specific views that previously existed.
  • Real-Time Synchronization: Established real-time data sync between core systems and the unified lake, enabling instant alerts, reporting, and global search capabilities.
  • Embedded BI & Analytics: Connected the unified data lake to downstream BI tooling (MicroStrategy) for embedded analytics and operational decision support.
  • Supporting Application Layer: Buyer and Store Portals, along with GoApps/BBIC, provide the interfaces through which regional teams access unified data insights, secured via Okta and API-managed through Apigee.

Technical Highlights

  • Data Consolidation Layer: Internal accelerators automated extraction and transformation of data from BigQuery, SAP HANA, MongoDB, and SQL Server sources into Databricks.
  • Cloud Infrastructure: Built on Google Cloud, using Firebase and PubSub for real-time event handling and Cloud Storage for supporting data assets.
  • Access & Governance: Implemented Unity Catalog for governance and data cataloging with automated information capture for new jobs and data assets.
  • Consumption Layer: MicroStrategy delivered embedded BI and reporting directly against the unified Databricks data lake.

Unified Data and Operational Efficiency

  • Data Modernization Outcome: Migrated and consolidated fragmented data from SAP HANA, BigQuery, and enterprise tools into a single governed Databricks data lake.
  • Reduced Manual Effort: Digitized workflows and automated data consolidation reduced manual effort by 40% across operations.
  • Scalable Growth: Architecture supports 10% annual store growth without performance degradation.
  • Real-Time Decision-Making: Embedded BI, instant alerts, and global search now run against a single source of truth instead of fragmented systems.
