Abstract: Systems, methods, and computer program products for managing an auction. A pool comprised of a first plurality of inventory items that are auction eligible is determined from an inventory item network based on inventory controls. A reference index is determined and assigned to each of the first plurality of inventory items in the pool. The first plurality of inventory items are filtered based on at least one inventory item characteristic to define a second plurality of inventory items. The second plurality of inventory items are filtered based on at least one constraint and the reference index associated with each of the second plurality of inventory items to determine an order in which at least some of the second plurality of inventory items are made available for bidding in the auction.

Abstract: Systems, methods, and computer program products for dynamically managing a travel object database that maintains one or more travel objects. A time limit request is received at a processing system for a record associated with one or more travel objects of the travel object database. A base time limit for a geographical identifier associated with the record is determined based at least in part on the geographical identifier by querying a time limit rules database based at least in part on the geographical identifier. The base time limit is adjusted based at least in part on the geographical identifier and at least one time adjustment rule to determine a geographical identifier time limit. A time limit for the record is determined based at least in part on the geographical identifier time limit to thereby transform the record and information thereof into a time limit for the travel objects associated with the record and maintained by the travel object database.
