method for providing data synchronization between a user's session, a data store storing a stored dossier and at least one external system, computer program product stored in a computer readable non-transient memory medium, and system for providing synchronization comprising a data store, a session comprising a user interface and arranged to access a stored dossier stored in said data store, and at least one external system which distinguishes itself by comprising a synchronizer communicating with at least the session. and data storage a method for providing data synchronization in a data processing architecture, including a data store (1), a client server or web server system for accessing said data store (1) and at least possibly heterogeneous external system, regardless of data (1). a version mixing mechanism handles the simultaneous updating of a given user data set in said data store (1) occurring when said data is simultaneously modified by the user and other processes operating on said external systems. A particular feature of said method is such that user-related data, including data from external systems, is saved without risk of loss, even if the user has started a user session and is working on it, and the user session. It is not forced to be saved until the user decides to do so. A system is described, with a system architecture that fits the disclosed method. Various system configurations and typical usage scenarios are provided.
