It didn't take Harvard Pilgrim Health Care long to figure out that the key to addressing changes in the insurance industry lies within an enterprise data warehouse. Their first IT system ran core applications and housed the data warehouse on an IBM mainframe. Years later, Harvard Pilgrim Health Care moved all of its business applications to Oracle and intended to move its data warehouse to Oracle as well.

However, during an extensive evaluation process, Ralph Miller, director of corporate information management, had major issues with the IBM mainframe and the Oracle environment. But, he found that Teradata performed outstanding in running fast queries, required fewer DBAs, was scalable and was simpler to support. In fact, after the evaluation process, Miller's team was charged with convincing upper management to "go with Teradata - even though the company had standardized on Oracle."

Now, Harvard Pilgrim Health Care is completing the migration, has launched a formal adoption program for user education, runs reports in minutes, and has already saved $1 million in infrastructure costs and improved performance.
