Order placement and acceptance management system and method thereof

An order placement and acceptance management system, comprising:

• an order database for storing order data, each increment of the order data being stored in a record of the order database;
• demand processing means for receiving values of attributes, including a code representing an order acceptant, of the order data in records that are designated by an order acceptant via a network;
• retrieving means for receiving the values of attributes from the demand processing means and retrieving a subset of the order data directed to the order acceptant, including at least one increment of the order data from the order database, the subset being determined at the request of the order acceptant, said subset having the values of attributes;
• transmission means for transmitting the subset of the retrieved order data to an order acceptant system via the network;
• and
• progress managing means for managing the progress of the order, where the progress managing means determines that the subset of the order data is defined as processed, on the basis of an input from the order acceptant system with regard to the subset of the received order data.
