The method and
system according to a preferred embodiment of the present invention allows
synchronizing the PNR values across a multi-
server (possibly multi-platform)
reservation system with an efficient and consistent mechanism. The mechanism addresses the consistency and performance issues thanks to its versioning and its lazy behaviour (the synchronization occurs only when required). It can be used as a solution during a migration phase from one
system to another with progressive migration of applications sharing data, and also as a permanent solution for distributed applications across different platforms. According to a preferred embodiment of the present invention, the reservation services are distributed between two different platforms (e.g. mainframe and open platforms) they require sharing the same Passenger Name
Record (PNR) contextual data in read and write mode to perform their business functionalities. The method and
system of a preferred embodiment of the present invention allows the synchronization of data (e.g. PNR data) which are shared in read and write mode across different platforms and across protocols of communication (e.g. TPF mainframe and open systems) so that the systems can share the same up-to-date PNR
context data
