    摘要： Systems and methods for synchronizing data stores. A framework including a sync runtime enables consistent and manageable synchronization between a data store and multiple, diverse back end data stores. The sync runtime provides services such as change enumeration, conflict detection, metadata management, item ID matching, sync interruptability, and the like that are accessible to configurable adapters over an application programming interface. Each synchronizing data store can uses a sync controller to initialize an adapter that can access the services provided by the sync runtime. The sync controller can use a profile to configure each adapter. The profile can identify conflict resolution policies, synchronization filters, source and destination folders, sync direction, and the like.

    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： 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： 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.

    摘要翻译： 可以解决同步期间检测到的更新 - 删除冲突，有利于更新或删除。 解决冲突有利于删除结果，在一个副本上删除的实体在所有选定的副本上被删除。 解决有利于更新的冲突导致更新的实体（包括从一个层次结构移动到另一个层次的实体）在所有选定的副本上复制。 为了解决有利于更新的冲突，删除被视为错误地报告。 被删除的实体以更新实体的形式复活。 更改版本信息保留在所有副本中。 更新 - 删除冲突可以根据各种解决方案策略进行解析，例如更新赢，删除胜利，特定设备上发生的更改胜利，以及最近的事件胜利。

    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： 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.
