Abstract:
1. A method, comprising: retrieving, by a computing apparatus, a working copy comprising one or more data items of shared data from a shared memory in which modifications or updates to the shared data are stored as publications in an unambiguous sequence, the modifications or updates stored in the shared data being associated with dualistic sequence information comprising unambiguous sequence references; detecting, by the computing apparatus, a publication that is performed after the retrieval of the working copy; generating, by the computing apparatus, in response to the detecting, deviation information indicating that there may be a local deviation from the unambiguous sequence; checking, by the computing apparatus, in response to updating a data item in the retrieved working copy, whether deviation information is provided indicating that there may be a local deviation from the unambiguous sequence; and if said deviation information is provided, using, by the computing apparatus, a deviated sequence when performing the update, otherwise using the unambiguous sequence.
