Eurotel

As the largest provider of wireless voice and data services in the Czech Republic, Eurotel serves 4.6 million registered customers. That kind of market penetration doesn't come easily in the telecommunications industry, but Eurotel has earned it, thanks to the highly refined business intelligence that helps the company attract and keep customers.

To more proactively address issues such as customer attrition, Eurotel consolidated disparate systems running on Microsoft SQL Server and Oracle into a single Teradata Warehouse. Eurotel's Jana Kolarova, Marketing Manager for the pricing and customer loyalty program, says the move to Teradata changed the way the company thinks about data. "Now we put all the information from various systems on one platform, which has completely different logic," she explains. "It changes the way we get information in addition to how we use that information."
