An Post Gives Its Postal Service a Boost
with Big Data and Analytics

An Post is Ireland’s national postal service and one of the country’s largest companies, providing a wide range of parcel and postal distribution, communication, retail, and financial services.


As one of Ireland’s largest and most reputable companies, An Post had big plans. Firstly, it wanted a solution to help seamlessly manage its millions of transactions every day; secondly, it wanted to offer new services to its customers to meet the increasing demands on modern post offices.

The company also wanted to enhance management reporting across operations, finance and HR, enabling real—time detailed insights across the business and improved efficiencies.


An Post deployed a big data and analytics platform using Oracle Exadata Database Machine, Oracle Advanced Analytics, and Oracle Database 12c innovations. Together, these solutions enabled readily available, enterprisewide business analytics to define, monitor, and drive business improvements.

The platform was also set up to reduce time to value on the company’s data capital, and—all importantly—to combat any instances of fraud.

The result was a real-time overview of An Post’s entire operations and the automatic consolidation of data from the largest electronic network in Ireland.

Oracle helped An Post consolidate data from the largest electronic retail network in Ireland, involving millions of daily transactions from 1,100 post offices.

Behavior and Fraud Detection

Owned by eBay, StubHub is the world’s largest ticket marketplace, enabling fans to buy and sell tickets to tens of thousands of sports, concert, theater, and other live entertainment events.
