Abstract: The invention concerns systems and methods for implementing systems that permit multiple, concurrent real time live or dynamic auction emulations in a networked environment. The systems include an auction database manager (ADM) component operatively linked to a rules based auctioneer (RBA) component and auction user interface manager (UIM) component. The ADM component manages data relevant to the auction environment such as bid parameters, lot data parameters, and user preference parameters; auction history data such as bid history data; and completed auction archive data. The RBA component manages the interactive nature of the live auction emulations by defining the parameters for data presentation to bidders, and causing the same to be delivered to relevant bidders via the UIM component. It also handles basic input and output calls to and from the ADM component.
