Abstract
This paper presents an efficient architecture to implement a catalog for its application in B2B electronic commerce. The architecture is designed based on a client-server model under the constraint of the unbalanced computing power between the buyer and suppliers. Computational algorithms are designed according to this assumption of limited computer resources at the client side and ample resources at the server side. The application is to provide a complete and workable catalog solution for price enforcement when fulfilling a purchase order to eliminate costs associated with having to make amendments to a past purchase order and having to delay a business transaction.
