Formed through a series of mergers, Oi is the largest telecommunications company in Brazil, with 10,000 employees, more than 31 million customers, and annual revenues of $14.5 billion.

“We needed a single view of the customer and faster updates to our enterprise data warehouse to support our programs. Informatica gave us the single platform we needed, and the agility to continue to lead in our market.”

— Vera Duarte, Enterprise IT Manager, Oi


Business Need

Marketing and Sales needed a single view of the customer to drive and manage up sell, cross sell and other marketing campaigns.

Customer service required a unified customer view to respond quickly to customer requests.

Product management needed to integrate various systems to bring products and services to market quickly and to support them effectively.

Management needed an up-to-date and comprehensive data warehouse to quickly respond to changes in market conditions and opportunities.

Management also needed high performance access to trusted data to minimize fraud and comply with mandated service level agreements.



Consolidate 17 customer databases into one 20-terabyte data warehouse.

Fast-growing data volumes led to unacceptable delays in the time taken to consolidate and load information into the data warehouse.
