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： 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.
摘要翻译：本发明的各种实施例涉及用于在硬件/软件接口系统环境中的对等计算机系统之间同步混合元件（ME）的系统和方法，该硬件/软件接口系统环境不允许在同步期间对大型非结构化ME滤波器进行快照。对于若干这样的实施例，该方法包括以两个步骤同步ME，一个用于快照ME的结构化数据组件（以及该文件流本身的cv，而不是该子串本身），一个用于锁定和传送该子串至接收到同步对等体，如果且仅当锁定后，从ME数据组件快照的时间确定文件流不变。

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： A protocol for replicating replicas in a sync community. Each replica maintains a knowledge that represents changes that the replica is aware of. Each replica does not typically maintain knowledge about other replicas. The protocol includes messages that include knowledge about changes on the various replicas. Using the knowledge, the replicas can enumerate changes and send the changes using asynchronous messages that do not need to be received in any particular order. The protocol enables filters to ensure that a valid replication is possible using a minimum knowledge argument. The protocol also enables replicas to partially replicate using filtered knowledge.
摘要翻译：用于在同步社区中复制副本的协议。每个副本都维护一个代表该副本所知的变化的知识。每个副本通常不会保留关于其他副本的知识。该协议包括包含有关各种副本上的更改的知识的消息。使用知识，副本可以枚举更改，并使用不需要以任何特定顺序接收的异步消息发送更改。该协议允许过滤器确保使用最小知识参数可以进行有效的复制。该协议还使复制品能够使用过滤的知识进行部分复制。

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.
摘要翻译：一种用于同步具有元数据和原始数据的数据库的系统和方法。元数据可能在两个系统之间完全同步，副本存储在两个系统上。可以选择性地同步原始数据，使得客户端系统不需要在本地存储所有原始数据。当断开连接时，客户端系统可以识别原始数据的某些部分在本地存储，并且当重新连接到服务器系统时，这些数据可以被同步。

摘要： Various embodiments of the present invention are directed to systems and method for detecting conflicts and applying conflict resolutions during manual and automatic conflict resolution operations. Several embodiments are directed to preventing both: (a) non-convergence of conflict resolutions, where partners can end up in a divergent steady state (i.e. have different data in the absence of outstanding conflicts); and (b) a non-terminating ping-pong of conflict resolutions between partners (which can occur with certain inefficient solutions that continuously update metadata for each conflict resolution without end). Certain specific embodiments of the present invention are directed to a method for maintaining knowledge that guarantees convergence of data, even when different partners apply different conflict resolutions.
摘要翻译：本发明的各种实施例涉及用于在手动和自动冲突解决操作期间检测冲突和应用冲突解决方案的系统和方法。若干实施方案的目的在于防止：（a）冲突解决的不一致性，其中合作伙伴最终可能处于不同的稳定状态（即在没有未决冲突的情况下具有不同的数据）; （b）合作伙伴之间的冲突解决方案不能终止乒乓球（可能会出现某些无效解决方案，不间断地更新每个冲突解决方案的元数据而无需结束）。本发明的某些具体实施例涉及一种用于维护知识的方法，以保证数据的收敛，即使当不同的合作伙伴应用不同的冲突解决方案时。

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.
摘要翻译：在同步社区中复制副本的系统和方法。同步社区中的每个副本都存储表示副本所注意到的更改的知识。由于每个副本都有自己的知识，因此每个副本不需要知道同步社区中多少副本或同步社区的拓扑。通过向知识发送更改请求，复制副本可以通过将其知识与接收到的知识进行比较来枚举复制的更改。复制后，知识将被更新。知识也可以包括知识变更ID，允许每个决议识别在进行特定更改时复制品知道什么。使用知识产权值用于检测复制期间的冲突。

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.
摘要翻译：将分级同步（同步）范围扩展到非分层场景可能涉及用于同步不同组织的数据存储的方法，包括将不同的物理组织映射到类似的逻辑组织，并利用基于组织的同步算法来同步不同组织的存储。此外，组织的唯一性限制也可能受到组织的父母子女排序限制的限制。
