摘要： A system and method for synchronizing a database having metadata and raw data. Metadata may be fully synchronized between two systems, with copies stored on both systems. Raw data may be selectively synchronized, so that a client system need not store all of the raw data locally. When disconnected, the client system may identify certain portions of the raw data to store locally, and such data may be synchronized when reconnected to a server system.

摘要： Various embodiments of the present invention are directed to systems and methods for synchronizing mixed elements (MEs) comprising structure data and unstructured filestreams between peer computer systems in a hardware/software interface system environment that does not permit snapshotting of large unstructured ME filestreams during synchronization. For several such embodiments, the method comprises synchronizing the ME in two steps, one for snapshotting the structured data component of the ME (as well as the cv of the filestream but not the filestream itself) and one for locking and transmitting the filestream to the receiving sync peer if and only if, after being locked, it is determined that the filestream is unchanged from the time of the ME data component snapshot.

摘要： A system and method for synchronizing a database comprising raw data and metadata derived from the raw data, but when the metadata has not yet been updated. The raw data and the metadata are first synchronized, with the raw data having been assigned a version number. After synchronization, any stale metadata will be updated and assigned the same version number as the raw data.

摘要： A uniform data structure contains a number of data fields. Some of the data fields are dedicated to contain information concerning the transfer of a data segment of a particular type (such as an XML segment) using one particular transfer mechanism (such as transferring as a string or DOM object, or transfer using an interface such as ISAXContentHandler, ITextSource, ITextSink, or IDOMSink interfaces). Other data fields are dedicated to contain information concerning the transfer of data segments of the same particular type using another transfer mechanism. When a module is to transfer a data segment, the module will cause the unified data structure to be altered as appropriate for the desired transfer mechanism.

摘要： Systems, methods, and computer program products for synchronizing items at replicas within a topology is disclosed. Items are stored in physical tables at the replicas. The physical table layouts at each replica can differ but are mapped to a common logical view. When a replica receives an indication that synchronization should be performed, the replica determines if changes have been made at the replica that should be mapped to the logical views. Replicas can facilitate this by comparing local change enumerations for changes made in physical tables to synchronization local change enumerations for changes in the logical views. Any changes that need to be synchronized are sent through the logical views to other replicas in the topology.

摘要： Systems and methods for replicating replicas in a sync community. Each replica in the sync community stores knowledge that represents changes the replica is aware of. Because each replica has its own knowledge, each replica does not need to know how many replicas are in the sync community or the topology of the sync community. By sending the knowledge with a request for changes, a replicating replica can enumerate the changes to replicate by comparing its knowledge with the received knowledge. After replication, the knowledge is updated. Knowledge may also include made-with-knowledge change IDs that permit each resolution to identify what a replica was aware of when a particular change was made. The made-with-knowledge values are used to detect conflicts during replication.

摘要： Update-delete conflicts detected during synchronization can be resolved in favor of the update or the deletion. Resolving the conflict in favor of the deletion results in the entity deleted on one replica being deleted on all selected replicas. Resolving the conflict in favor of the update results in the updated entity, which includes an entity moved from one hierarchy to another, being replicated on all selected replicas. To resolve the conflict in favor of the update, the deletion is treated as though it were reported erroneously. The deleted entity is resurrected in the form of the updated entity. Change version information is maintained in all replicas. Update-delete conflicts are resolvable in accordance with various resolution policies such as the update wins, deletion wins, changes occurring on a particular device wins, and most recent event wins, for example.

摘要： Tombstones can be removed from a data store without data corruption. Tombstones placed into a forgotten knowledge list can be compared against each other and/or items in a tombstone table, and deleted when tombstones representing subsequently deleted items are extant. Also, creation database version information can be kept along with database items, and databases can record database version information when they synchronize. If a synchronizing database discovers an item that it does not have, but the creation database version information associated with the item reflects that the synchronizing database “should” have the item, then it can be inferred that the item was subsequently deleted, and item resurrection can be prevented.

摘要： Extending hierarchical synchronization (sync) scopes to non-hierarchical scenarios may involve a method for synchronizing differently organized data stores comprising mapping different physical organizations to similar logical organizations and utilizing an organization-based synchronization algorithm to synchronize the differently organized stores. Also, the uniqueness constraints of the organizations may be preserved as well as the parent-child ordering constraints of the organizations.
