Abstract: A system for providing reservation data is presented. The system includes a reservation data system interface that receives reservation data, such as the availability of rooms and rates for such rooms, and update data, such as when rates change or rooms are reserved, from two or more reservation systems, such as central reservation systems for two or more different hotels. A master reservation system receives the reservation data from the reservation data interface and stores the reservation data in a database, and updates the database with the update data. A user interface system coupled to the master reservation system receives reservation request data and provides updated reservation data in response to the reservation request data.

Abstract: An interface controller for managing operation of a plurality of devices via a wide area network is provided. Each of the devices has a unique communication protocol associated therewith. A network communications layer is provided for communicating with the plurality of devices via the wide area network and a client application associated with the plurality of devices. An information processing layer is also provided for communicating with the network communications layer. The information processing layer has a set of objects corresponding to each of the plurality of devices. The information processing layer is also for interacting with a data access layer on behalf of each of the plurality of devices using the corresponding objects. Interaction between the information processing layer and the data access layer on behalf of all of the plurality of devices is governed by a single set of rules.
