Waltham, Mass.--IMarket Inc., a D&B company, this week announced it had strengthened its b-to-b database with the addition of several new data elements from D&B, including details on energy usage, credit worthiness and minority-ownership status. IMarket customers can access the data through the MarketPlace desktop suite as well as the company's Internet solution, zapdata.com, now enhanced with a save-and-restore feature that allows users to build targeted prospect lists and save the list criteria for future use.
