A system including an Internet based server running a central data repository database, and deploying spiders to scour the Internet analyzing the millions of product-oriented web pages and newsgroup postings, plus a server application for classifying and indexing all of the information derived from the spiders. The web server pushes downloadable—“Rich Internet Application” (RIA) client application to subscribers running client devices. The RIA client application is accessible directly from any other enabled native application to draw information from the central data repository.
