Türk Telekom, a leading communication and convergence technology company in Turkey and the country’s most valuable brand for the last four years according to Brand Finance, provides fixed line communications and broadband internet services. The company, which was founded in 1994 by separating from Posta ve Telgraf Teşkilatı, the national post and telegraph directorate of Turkey, owns more than 14.5 million fixed access lines—nearly all fixed access lines in Turkey—and 7 million asymmetric, digital subscriber lines.
Türk Telekom required faster development of telecommunications operation, sales, and marketing reports to be derived from approximately 20 terabytes of data collected from mission-critical applications, like billing and customer relationship management (CRM) systems. The company also needed to ensure replication in a hybrid environment with source systems and target systems from different manufacturers in two geographical locations. To meet these goals, Türk Telekom established the first and only asynchronous, real-time archiving solution in Turkey with Oracle GoldenGate to facilitate real-time data warehousing with hybrid online replication from 16 different source systems to one target data warehouse with near-zero latency. Thanks to the new solution, the company was able to eliminate 30 hours of database downtime, reduce costs, and save approximately US$22 million.
“When we decided to find a replication tool, we evaluated some competing products. When we saw the results delivered by Oracle GoldenGate, our choice was clear,” said Serkan Karatas, database division manager, Türk Telekom. “Oracle GoldenGate offers more advanced replication features, lower maintenance costs, and more flexible configuration options than its competitors. In addition, Oracle GoldenGate produces much less overhead for source systems.”
Türk Telekom acquired GoldenGate licenses from Asseco SEE, which was GoldenGate’s distributor in Turkey. The implementation was performed by Türk Telekom’s internal teams while Asseco SEE provided consultancy services to resolve operational issues that needed specialized experience.
