Method and system for implementing multiple exchanges within a common instance

摘要

A multiple exchange instance for facilitating business to business e-commerce. The multiple exchange instance includes a plurality of exchanges. Each of the plurality of exchanges are implemented within a common instance. The plurality of exchanges share a set of common components to avoid redundancy. The plurality of exchanges are each provided with a respective view having respective unique components as per the requirements of their respective exchange operators. The multiple exchanges within the common instance facilitate communication between the exchanges. The multiple exchanges each have their respective users, and the common instance allows the users to perform input/output using the common components. The multiple exchanges are configured to use communication protocols to communicate with processes external to the common instance. The common instance is implemented using a database program running on one or more computer systems.
