💡 Why This Project Matters

Many retail organizations collect massive volumes of transactional data but struggle to transform that information into meaningful business insights. Without proper reporting and analytics, decision-makers cannot easily identify revenue trends, customer behavior patterns, product performance, or growth opportunities.

This project demonstrates how DeTLeng converts raw operational data into executive-level dashboards that support data-driven business decisions.
