PROBLEM TO BE SOLVED: To provide a system and method for room inventory management.SOLUTION: An inventory record module generates inventory records for rooms for a predetermined time period. Each inventory record may include: an inventory record index representing a physical property of an associated room; and an inventory record attribute representing a modifiable attribute of the associated room. A key generation module generates keys to identify one or more of the inventory records on the basis of attributes associated with the keys. Each key may include a key index that matches an inventory record index for one or more of the inventory records. A query response module receives selections of the keys from the generated keys, and a virtual room pool generation module generates virtual room pools by grouping the selected keys for each of the selections and the inventory records identified by the selected keys for each of the selections.
