Turkcell Consolidates Data Warehouse With Oracle

Turkcell, a mobile
communications and technology company in Turkey, managing more than 1.2PB of
data, implemented a new data warehouse system that included Oracle Exadata Database Machines to
achieve performance and scalability.

Each day, Turkcell’s communications network
generates about 1.5 billion call detail records (CDRs), the computer records
containing details of every phone call that passes through the network. The
CDRs, along with other business information, adds up to more than one petabyte.

Using Exadata at the core of its data warehouse
system helped Turkcell drive increases in reporting speed – a
critical improvement for hundreds of business users who run more than 50,000
reports each month to help track market trends, analyze finances, and refine
business strategies.

In the previous environment, it took about 30 minutes to generate a typical
report and as much as four hours or more for more complex analyses. Today,
reports are running almost 10x faster and about 90% of all reports take less
than five minutes to run.

By consolidating on Exadata,
Turkcell shrank its floor space needs by 90% and reduced its energy consumption
by 80%.

At Oracle OpenWorld San Francisco 2012,
Ferhat Sengonul, Data Warehouse manager, Turkcell was recognized as Data
Warehouse Leader of the Year for this data warehouse implementation
that took 10 weeks to deploy.

Ferhat Sengonul and his team at Turkcell
are responsible for architecting and implementing Turkcell’s data warehouse.

The award, one of several categories covered
by the Oracle Excellence Awards, honors individuals who demonstrate excellent
technical knowledge and innovative use of Oracle data warehouse technologies to
the benefit of their business.
