An Online Real-World Unified Data Architecture: Bridging Digital Analytics and Transactions in Practice
Quickie (INTERMEDIATE level)
Banquet

Most organizations collect digital analytics and transactional data in parallel — but rarely together. The result is a fragmented view of the customer: behavioral signals that never inform business decisions, and transactional models blind to how customers move through digital products.

This session presents a real-world implementation of a unified data architecture that bridges this gap. Starting from a full re-instrumentation of web and app tracking via a structured data layer and tag management, the pipeline progresses through GA4, Big Query and Azure Databricks — where digital events are joined with transactional records at the customer level.

The talk covers the architectural decisions behind a scalable, uniform event schema; a multi-dimensional data model across platform, device, channel, customer / personalization segment, and registration status; and the engineering of automated reporting pipelines in Power BI.

The second half focuses on the Machine Learning opportunity this foundation unlocks: customer segmentation on combined behavioral and transactional features; propensity scoring for deposit, bet, and reactivation events; churn prediction catching early signals weeks before the last transaction; and CLV modeling enriched with digital context.

A key theme is the unregistered user — invisible to transactional systems but rich in digital intent — and how behavioral data enables scoring and nurturing this audience before they ever register.
