The system, which replaced a wide variety of disparate databases, has improved the accuracy of information available to users by cutting inefficiencies, said Paul Tully, head of management information services at Vodafone Ireland.
For example, he said, the company has already saved £675,000 in revenue assurance - ensuring customers are paying for what they use. In addition, customer service has improved because call centre staff can access information on a single screen, rather than having to use five screens, as was the case previously.
"The main advantage for us is that we are using the data once rather than going through multiple databases," said Tully.
Operating a single datawarehouse will lead to further cost savings as Vodafone Ireland will not have to build extra platforms as new data feeds are created, Tully said.
"We are in a fast-moving business which creates new requirements all the time, so you have to be able to move quickly," he said. "We will avoid the extra costs of new data feeds and will be able to produce information more quickly."
The Teradata platform will also mean Vodafone Ireland is well placed to support the growth in non-voice services, such as SMS, picture and video messages, Tully said.
"We are not worried about the volume of data - with this platform we will be ready," he said. "We already derive about 20% of our revenue through data services, so we are used to handling it."
