Electronic product catalogs (e-catalogs) are becoming an essential component of Internet and Intranet-based procurement solutions to all businesses as they provide key support at the information-gathering procurement stage. We consider single e-catalog system for small and medium businesses as a part of Government support e-Business plan.
