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. To give sales, service, marketing, and management the business intelligence necessary to stay competitive in a heated market, Oi needed to manage its customer data faster and more effectively.


  • Consolidate 17 customer databases into one 20-terabyte data warehouse
  • Integrate data across multiple back-end systems
  • Update systems in near real-time
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.
