Designed to provide access to existing and new reports to Corporate Express customers via the Web, the online service will allow users to view procurement data using at-a-glance dashboards, standard reports and by drilling down to transaction-level data for more detailed investigation. While developing the solution, Corporate Express selected Netezza for its high performance and ability to handle mixed workloads.

“We set out to develop an online service that would enable our customers to have simple and intuitive access to the intelligence related to their office supply purchases,” said Matt Schwartz, director of Business Analysis for Corporate Express US. “And after evaluating numerous data warehouse solutions, including Teradata, we chose Netezza for this essential customer-focused initiative due to Netezza’s ability to power our needs for rapid response and performance when thousands of users could be accessing the service.”
