Introduction
Delta Community Credit Union, Georgia’s largest credit union, serves more than 360,000 members and operates 27 branch locations. As the organization grew, so did its data challenges. Reports were built manually in spreadsheets by a handful of “data wizards,” leaving leadership with outdated, siloed information. To better serve its members and make faster business decisions, Delta Community needed a single, reliable source of truth for its data.
Pre-WhereScape Challenges
- Data trapped in spreadsheets: Reporting relied on manual manipulation by a few experts.
- Lack of centralized access: No single repository for enterprise data.
- Slow delivery: Early data warehouse efforts took over a year, with minimal progress.
- Limited resources: A small team and tight budget following a major infrastructure investment.
- Rising business demand: Leadership needed actionable insights, at speed.
“Most of our data lived in spreadsheets and we didn’t have a central repository. A small group of spreadsheet ‘wizards’ would bring all the data together, prepare it, manipulate it, and produce reports.”
– Su Rayburn, AVP of Information Management and Analytics, Delta Community Credit Union
The Solution: Accelerating Time to Value With Automation
To meet the growing demand for insights, Delta Community Credit Union turned to data warehouse automation. After evaluating multiple options, the team chose WhereScape RED for its ability to automate design, development, and deployment directly on Teradata.
WhereScape RED generated Teradata-native objects; including tables, models & indexes and automated set-based loading procedures. This allowed the small team to quickly build a high-performance enterprise data warehouse without relying on extensive custom code.
Once the first projects were successfully delivered, Delta Community adopted WhereScape 3D to further automate data modeling, planning, and testing, streamlining their entire data lifecycle.
“WhereScape RED was the only solution that would really let us take advantage of the massively parallel processing power of Teradata. And because it automated nearly everything, we could stretch every dollar in our budget.”
