摘要： A system and methods for synchronizing information in datasets via a communication medium are provided that are suitable for synchronizing even across communication mediums that are susceptible to high latency, non-FIFO (non-First-In-First-Out) delivery order, or other adverse characteristics. According to an aspect of the invention, a computer-implemented method is for synchronizing user data in a first dataset with user data in at least a second dataset via a communication medium. The user data in the first dataset and the user data in the second dataset are capable of having been independently modified prior to the synchronization. The method includes sending a dataset change from the first dataset, receiving the dataset change via the communication medium, and determining whether the received dataset change, hereinafter referred to as the just-received change, was sent earlier than another dataset change, hereinafter referred to as the previously-received change, from the first dataset that was received earlier than the receiving step. The method further includes performing synchronization of the first and the second datasets based at least in part on the determining step. The performing step includes refraining from propagating the just-received change into the second dataset, if the just-received change is determined in the determining step to have been sent earlier than the previously-received change. The performing step further includes propagating the just-received change into the second dataset at least to an extent needed for reconciling the just-received change with the second dataset, otherwise.

摘要： A synchronization system providing multi-client synchronization is described. By storing the data that is actually being synchronized (i.e., storing the actual physical body of a memo, for instance) inside an extra database, “Grand Unification Database” (GUD), (or by specially-designated client data set) under control of a central or core synchronization engine, rather than transferring such data on a point-to-point basis, the system of the present invention provides a repository of information that is available at all times and does not require that any other synchronization client (e.g., PIM client or hand-held device) be connected. The GUD provides a super-set of the other client data sets. Therefore, if the user now includes an additional client, such as a server computer storing user information, the synchronization system has all the information necessary for synchronizing the new client, regardless of whether any of the other clients are currently available. The system can, therefore, correctly propagate information to any appropriate client without having to “go back” to (i.e., connect to) the original client from which that data originated.

摘要： A system and methods for synchronizing datasets are provided that are especially suitable and efficient for a user who has three or more datasets that need to be occasionally synchronized, with no one dataset or synchronization system being guaranteed to participate in every synchronization. Synchronization status information, such as correspondences between data records of particular multiple datasets, is stored with more than one of the datasets. When two datasets that contain synchronization status information synchronize with each other, they not only synchronize user data and exchange status information involving each other, but they also synchronize and exchange status information involving “third-party” datasets that may not be participating in the synchronization. In this way, synchronization status information collected in an earlier synchronization is made available in a later synchronization, even if the earlier and later synchronizations are not conducted by a same synchronization system or do not both include a common, permanently designated “hub” dataset. Further, when datasets being synchronized are found to contain mutually-duplicative data records, the data records are intelligently mapped to each other as being corresponding so as to avoid or minimize causing of changes to be made, in the data records, that would make synchronization status information stored in another dataset to become obsolete.

摘要： Synchronization system and associated methods provide synchronization of an arbitrary number of datasets, including more than two datasets. To achieve this, a reference dataset is used to store a super-set of the latest or most-recent data from all user datasets to provide a repository of information that is available at all times. Therefore, if the user later wishes to synchronize a new user dataset, such as one in a server computer that stores user information, the system already has all the information necessary for synchronizing the new dataset, regardless of whether any of the other datasets are then available. Further, to simplify use, a unified user interface is provided that allows the user to easily determine which of his or her datasets are currently set to be synchronized and allows the user to conveniently alter the current settings to select one, two, or even more than two clients for synchronization. Various “conflict” or “duplicate” resolution strategies are described for intelligently handling complexities resulting from allowing synchronization for an arbitrary number of datasets and allowing synchronization using even data from datasets that are not available. Architectural support for “plug-in” client accessors and type modules is also provided. This allows support to be added for new datasets or new types of data merely by developing and plugging in new, compact client accessors or type modules, without updating or replacing the core synchronization engine.

摘要： A sync server responds to messages from a client to synchronize data between a client dataset and a reference dataset. Various messages may be received from the client, including changes to the client dataset, requests for confirmation of received changes, or requests for changes to the reference dataset. When the server receives client changes, the server reads record ID's from the messages, writes the ID's into a change ID list, and places the changes into a queue for processing. When the server receives a request for confirmation of changes, the server uses the change ID list to confirm receipt of changes, including changes that have not yet been processed. If the server receives a message that requires that the reference dataset be up-to-date, such as a request for changes from the reference dataset, the sync server processes all of the changes in the queue before processing the new message.
