Why Oracle

Tata Sky decided to upgrade to Oracle Database 11g Release 2 as the company wanted to improve its system performance to support future data growth.    

“We didn’t even consider other vendors, as we have been familiar and comfortable with Oracle products for years. Oracle Database is highly available, secure, scalable, and cost effective. The upgrade seamlessly replaced the existing database, which is critical for our 24/7 television service,” said N. Ravishanker, CIO, Tata Sky Ltd.

Implementation Process

Tata Sky completed its Oracle Database upgrade and Oracle Real Application Clusters implementation project in June 2013. It finished the project on time and without business disruption.


Tata Sky engaged Oracle partner Tata Consultancy Services as the system integrator for its Oracle Database upgrade.  

“We are very happy with Tata Consultancy Services expertise and experience with Oracle Database, which enabled us to handle massive data volume everyday and support our future growth,” Ravishanker said.
