The method and system according to a preferred embodiment of the present invention allows ensuring consistency of the PNR record when it is handled within the subsystem controlled by the reservation interceptor module and including a plurality of OBEs. According to a preferred embodiment of the present invention the PNR context on open systems is centralized to avoid its fragmentation in the distributed environment, as gathering of all the context parts implies performance issues. In addition, instead of implementing a transaction session protocol to handle a start of transaction, intermediate updates and a final commit or rollback on the PNR context, the principle of the service interceptor architecture is to delegate the functional queries with the current user PNR context which will be modified in the central repository of PNR context only at response time when the whole functional use-case is finished.
A reservation method operating on a distributed reservation system including a plurality of Open Back End servers (OBE), each OBE being adapted for providing a service, for controlling consistency of PNR record during a user transaction across at least two OBEs, the method including the steps of:
A computer program comprising instructions for carrying out the steps of a reservation method operating on a distributed reservation system including a plurality of Open Back End servers (OBE), each OBE being adapted for providing a service, for controlling consistency of PNR record during a user transaction across at least two OBEs, when said computer program is executed on a computer, the method including the steps of:
A reservation sub-system including:
