TOKYO, Feb. 14, 2013 /PRNewswire/ --Teradata (NYSE: TDC), the analytic data
solutions company (Teradata Japan, Minato-ku, Tokyo; Yukihiko Yoshikawa,
President), today announced that Yahoo Japan Corporation (Headquarters:
Minato-ku, Tokyo; President and CEO, Manabu Miyasaka) has renewed and updated
its analytical data systems with the Teradata Active Enterprise Data Warehouse
Platform 6690, Teradata's latest high-end model, for its data warehouse (DWH),
the largest DWH analytics platform in Japan.


Due to the rapid increases in data volume and user requirements for
state-of-the-art big data analytics, Yahoo! JAPAN needed to bring its DWH
capabilities and performance up to date. Yahoo! JAPAN renewed and upgraded to
the Teradata 6690, which has a larger capacity and higher performance –
designed with multiple tiers of storage technology including main memory and
both high-speed and high-capacity storage drives – to achieve optimum data
warehouse performance.

Yahoo! JAPAN has also implemented a new application known as "Access-Navigator
Web," a web-based data search tool. This software enables an employee without
training in SQL to perform data analysis – by freely manipulating and
integrating data on the new Teradata system. This lowers employee learning
curves for SQL training and increases the number of users who can perform

At Yahoo! JAPAN, more than 250 employees now use the Teradata analytics
platform every day for their tasks, such as visualizing and analyzing enormous
volumes of data traffic across many services, including search, shopping, and
auctions. They also measure the business impact of marketing and advertising
campaigns and drive the development of new services.

Because "Yahoo! JAPAN" is today the largest portal site in the country, its
Teradata Active DWH now manages about 120,000 queries daily. The deployment of
the newest Teradata technology, completed at the end of November 2012,
provides high efficiency and speed – with response times now running 200 to
250 percent faster than the prior systems.

Yahoo! JAPAN expects the number of users will grow as requirements and data
volume increase. In addition, there will be a growing need to leverage past
data for chronological comparisons, while storing detailed data such as
sampled access logs and advertisement logs.

Yahoo! JAPAN is assured that the organization will continue to see increasing
data volumes, and will benefit from the new system's Teradata database
columnar functionality. The company also sees smart phone traffic growing – a
major pillar driving future revenue – and is committed to providing speedy
customer service.

"Yahoo! JAPAN" first built its data warehousing environment with Teradata
technology in 2002 as an analytical database system for several in-house

The latest Teradata Database software provides hybrid capabilities,
integrating column and row technology, and market-leading innovations that
enhance workload management, multi-temperature data usage, temporal data
capability, security, and application portability.
