Replacing a legacy BI system and building a modern data platform
A data platform modernization engagement focused on replacing legacy BI, integrating fragmented enterprise data, and improving reporting reliability at scale.
Problem
A legacy business intelligence solution was expensive to maintain, inflexible, and required significant manual effort to prepare data for reporting. Data was fragmented across multiple enterprise systems, including ERP platforms, databases, and external APIs, making it difficult to produce reliable and consistent insights.
Solution
We designed and implemented a modern data platform that replaced the legacy BI system and unified data across the organization.
Approach
- Decommissioned a legacy BI solution and replaced it with a modern data architecture.
- Integrated data from multiple enterprise systems, including SAP, JD Edwards, SQL Server databases, and external APIs.
- Built scalable data pipelines for ingestion, transformation, and storage.
- Implemented data enrichment and transformation using Databricks.
- Applied medallion architecture (bronze, silver, gold layers).
- Implemented Slowly Changing Dimensions (SCD) for historical tracking.
- Established data quality checks and validation processes.
Outcome
- Reduced infrastructure and licensing costs by approximately $250,000.
- Replaced a rigid legacy reporting system with a scalable data platform.
- Reduced manual data preparation effort.
- Improved consistency and reliability of reporting.
- Enabled a foundation for future analytics and decision-making.
