Turkcell İletişim Hizmetleri A.Ş. (Turkcell) is a leading provider of mobile communications in Turkey, with more than 34 million subscribers. Established in 1994, Turkcell created the first global system for a mobile communications network in Turkey, and it was the first Turkish company to be listed on the New York Stock Exchange.
Turkcell needed to process up to 10 billion daily, call-data records (CDRs) and value-added service logs for billing and to ensure continuously accelerated development of 4,000 distinct reports containing critical business data. The company combined two Oracle Exadata Database Machine X2-2 HP Full Racks to reduce the size of the company’s data warehouse from 600 TB compressed to 60 TB and enable more than 500 data warehouse users to generate more than 100,000 reports per month—twice as many reports as with the deployment on its previous, single Exadata machine. Turkcell also shortened project execution times substantially and future-proofed its storage capabilities, thanks to Oracle Exadata Database Machine’s effortless scalability.
Working with Oracle Consulting, Turkcell implemented 16 nodes on two Oracle Exadata Database Machine X2-2 HP Full Racks in just five days, without any interface changes.
“We did not ask any other vendor for a proof of concept because it would require them to work on a migration project that would last one or two years, and it is difficult to see the end for such a project. With Oracle Exadata, we migrated without any design change or development change, simply plugging in the new technology,” said Ferhat Şengönül, data warehouse specialist, Turkcell İletişim Hizmetleri A.Ş.
“With assistance from Oracle Consulting, we implemented 16 nodes of two Oracle Exadata Database Machines X2-2 HP Full Rack in just five days, without any interface changes,” Şengönül said. “Oracle Consulting was also very fast in resolving issues that we faced during the post-implementation phase. With the excellent support from Oracle Consulting, all issues were resolved quickly.”
