As the number of buyers and suppliers available for online transactions increases exponentially, a detailed understanding of the complex interactions among customers, partners and suppliers becomes an integral part of every company's supply chain.

With the delivery of Informatica CommerceAnalytics for Ariba ORMS, Informatica and Ariba will directly address the analytic requirements for optimizing commerce and other supply-chain operations.

Informatica CommerceAnalytics for Ariba ORMS will extract data from the Ariba ORMS B2B procurement solution and populate a pre-built analytic application. The results will then be presented to a variety of business decision-makers, including procurement managers, financial and other operations analysts, as well as everyday purchasing managers, through a suite of robust analytic applications. With critical analytical information in hand, these business analysts will be empowered to make better decisions - decisions that can lower costs, improve service levels, and optimize commerce processes.

"In the competitive landscape of B2B e-business, winning companies must maintain a sophisticated understanding of their business across multiple channels and accounting for many variables within a complex web of customer, partner and supplier relationships," said Diaz Nesamoney, president of Informatica. "Informatica's software platform provides an essential component of Internet infrastructure - a flexible backbone that integrates data from multiple transaction systems and enhances it for analysis. By pairing its Ariba ORMS B2B procurement solution with our joint analytic solution, we believe Ariba will be positioned well ahead of its B2B e-commerce competitors in giving customers the insight they need to optimize the performance of their e-businesses."
