Cable & Wireless Optus has contracted NCR division, Teradata for an undisclosed amount to supply its data warehousing standard operating environment.
Under the terms of the three-year agreement, Optus will use the company's warehouse solutions as the first step in implementing a new enterprise data warehousing strategy.
Julia Bowen, director of programs for Optus, said the telco was moving to ensure it got the most out of its customer data.
"We have various customer markets and we are looking to consolidate customer information across the company.
"It is really about economies of scale so we are only cleaning the data once."
Bowen said the data warehouses were used mainly for marketing information and campaigns, and for financial reporting.
Across Optus about 150 systems are in use. "Most of our application and data centre support is outsourced anyhow.
"We use various technologies within our data centres. We had been using a solution for eight years which the Teradata solution has replaced. We also use an Oracle-based data warehouse solution, mainly for reporting purposes."
