Abstract: A method of integrating large volumes of updates in a database system. Each individual update includes of a coherent set of data records supplied by a data provider. The database system includes a master file repository and an active image repository. The method includes first obtaining for each individual update a unique modification identifier from a logistic table of the database system. The master file repository is then updated with the coherent set of data records of each uniquely identified individual update. A unique commit identifier is further obtained from the logistic table for each individual update that has been committed by the master file. The active image repository is synchronized by successively loading into the active image each individual update. Completion of the propagation of each individual update into the active image repository is achieved when the loading of each corresponding set of data records is committed by the active image.

Abstract: A ticket change constrainer which allows reissuing or revalidating an already issued airline ticket includes a ticket change domain reducer operable to reduce an input search domain of change opportunities on the basis of change conditions set in the already issued ticket. It also includes a ticket change valuer operable to weigh the change opportunities of the reduced search domain and to return a reduced valued search domain of change opportunities. The weighing of the change opportunities is done on the basis of pricing method popularity scores updated in a ticket change memory by a ticket change watcher agent from actual change transactions handled by the system. The change conditions include standard pricing methods of the airline industry. The input search domain of change opportunities is produced by a conventional fare-driven search engine on the basis of a ticket change request issued by an end-user of the system.

Abstract: A method of evaluating outbound and inbound fare amounts out of a plurality of roundtrip fare recommendations is disclosed. Intended to be displayed in a one-way like display, roundtrip fares are first obtained from a fare-driven availability engine receiving inputs from an online user of a travel website. Further recommendations are deduced by combining the above roundtrip fare recommendations in order to obtain a first improved list of recommendations which comprises more outbound and inbound fare combinations. Then, one-way fare amounts are determined for each combination from the first improved list of recommendations. A second improved list of recommendations, comprising outbound and inbound fare amounts evaluated on the basis of the initial roundtrip fare recommendations, is generated. Outbound and inbound fare amounts can thus be shown in a one-way like display of roundtrip fares to the online user of the travel website.

Abstract: A method and system for making roundtrip air flight reservations includes an end-user receiving a response having departure dates with a lowest cost outbound fare for each date and return dates with a lowest cost inbound fare for each date, outbound flight and inbound flight segments each priced with One Way Combinable fares, the One Way Combinable fares can be priced independently of all other One Way Combinable fares (i.e. restriction on covered segment, fare amount can be doubled to price the Round Trip) and can be combined together with any other One Way Combinable fare (i.e. no combinability restriction) in order to form a guaranteed pricing solution regarding IATA regulation both in domestic and international contexts for complex segments (i.e. based on non-direct flights).

Abstract: A method of insuring the integrity of a plurality of updates brought in real-time to a production database concurrently used by one or more software applications is described. The production database includes a plurality of products participating to the definition of objects. The method first includes requesting the issuance of a unique filing number associated to a draft state version of the plurality of updates while keeping them invisible to the end-users of the production database. Then, a set of product items identified as a whole by the unique filing number are created or copied from the production database and gathered under the form of a meta-product on which the plurality of updates is applied. After updating, the meta-product is successively set into a customizable flow of one or more validation states in order to perform a cross-validation of the plurality of updates.

Abstract: A method for loading flight schedule modifications in an air travel computerized reservation system, wherein: the flight schedule database is updated; the reservations concerned by the flight schedule modifications are reassigned to update the reservation inventory database. The method for loading flight schedule modifications includes the following steps: receiving at least one lot of modifications containing flight schedule modification data, retrieving individual modifications contained in the lot and storing in a register in the form of records for future scheduling, simulating reassignment of the reservations concerned by the flight schedule modification, by accessing with the reservation distribution server both the records and the flight schedule database, final updating of the flight schedule databases and of the reservation inventory. The method is useful for updating databases during flight schedule modifications in computerized reservation systems.

Abstract: In a method for automatically mapping a cabin and travel class structure of an disrupted flight into replacement flights, cabin and travel class structure of the disrupted flight are retrieved. For each affected passenger, a base disrupted flight is determined from the passenger itinerary. For the disruption period, cabin and travel class structure of the replacement flights are split into sub-periods. For each sub-period, mapping begins by establishing a direct match between cabin and travel class structures. The direct match is validated against actual cabin and travel class structure of the replacement flights, including pinpointing all found discrepancies. All class matching tables (CMTs) applying to the disrupted flight and disruption period considered are retrieved from a rule repository. Cabin and travel class structure of the replacement flights are further split in sub-periods to imbed the actual validity periods of retrieved CMTs. Rules of the retrieved CMTs resolve all found discrepancies.

Abstract: The invention concerns a method and a system for maintaining consistency of a cache memory, accessible by multiple independent processes. The processes can share common data. The processes perform simultaneous data searching operations optionally followed by providing the data to the processes, a removal of same or an insertion of new data. The searching, removal and insertion operations, are comprehensively executed once they have been initiated by the independent processes. They are executed excluding one another when they must operate on common data. The removal or insertion operations are each completely reversible. In that context, the invention provides that the operations for providing, removing or inserting the data have a finite or bound duration of execution so as to prevent any locking.

Abstract: A method and a system for generating personal promotion codes from the computing resources of a provider of services. Internal promotion codes including a family ID field and serial ID field of alphanumeric characters are first generated. The internal promotion codes are then encoded into a corresponding series of external promotion codes of alphanumeric characters, which render the internal promotion codes unintelligible. After which the series of external promotion codes is packed into an encrypted file which is forwarded to a client application of the provider of services to have the external promotion codes distributed to its customers. The external promotion codes later submitted to the client application by the customers are further validated by the provider of services. Validation of the external promotion codes submitted by the customers does not require that all generated external promotion codes need to be stored in a database of the provider of services.

Abstract: A computerized travel system and a method for providing advices and warnings per travel destination to end-users. The system has a client service module for receiving queries from the end-users, and delivering to them merged reports of travel advices and warnings for the queried travel destinations. A download and parsing module parses travel raw documents, downloaded from a plurality of online reliable travel sources, into cleaned raw documents sharing a common formatting structure including sections, sections headers and paragraphs. An algorithmic module integrates the cleaned raw documents into the merged reports of travel advices and warnings per travel destination. The integration is performed from a base document chosen among all the relevant clean raw documents for each queried travel destination. Comparable sections are determined on the basis of contents of their section headers and semantically close paragraphs are placed next to each other in corresponding sections of merged reports.

Abstract: A method and a system keeps travel data consistent between a database of airline reservations storing passenger name records (PNR's) including travel segments, and a database of electronic tickets (E-tickets) including travel coupons, this latter database being independently controlled from a ticketing server. Whenever a travel segment is updated or added in one of the PNR's an electronic reconciliation service (ERS) receives images of updated PNR's. Corresponding E-ticket images are requested by ERS and received from the database of E-tickets. Then, ERS establishes a matrix of links between orphan PNR travel segments and orphan E-ticket travel coupons so that E-ticket orphan travel coupons are re-associated with matching PNR orphan travel segments. After E-ticket is updated it is revalidated or reissued. Optionally, a penalty generator calculates penalty fees on the basis of changes brought to the revalidated or reissued E-tickets. The penalty fees are then attached to the updated PNR's.
