A campaign can generate plenty of clicks without showing whether it produced sales. Operational data helps close that gap: it is information generated by internal systems that support routine business activity. Purchase records from a website, point-of-sale system, or billing system can show what customers bought, how often, and through which channel. When a business collects those records directly, they are also first-party transactional data. section 2.3.1 section 1.4.3
Operational business data is one category in a broader sourcing picture that also includes customer and engagement data, marketing performance data, external intelligence, and privacy and compliance data. The categories serve different decisions. A purchase record establishes an order or sale; an email open indicates engagement. Comparing the two can reveal opportunities that neither record shows alone. section 2.3.1 section 1.4.3
From store loyalty to online sales
An apparel brand found customers who bought regularly in-store and opened its emails but rarely purchased online. By comparing purchase records with email engagement, it identified an audience for limited-edition products offered exclusively online. The campaign increased digital revenue and average order values. section 1.4.3
For measurement, connect transaction records—revenue and order details—to audience and campaign data using a consistent customer identifier. This makes it possible to assess campaign ROI rather than relying only on clicks or opens. Protect customer privacy and obtain appropriate consent, especially when combining records from multiple sources: useful linkage must not come at the expense of trust. section 7.7.5 section 2.3.1
