摘要： Methods and systems to maintain data integrity across a plurality of devices by reducing or preventing dangling references are provided. In one embodiment, all data objects are provided with reference IDs enabling reference to an extant version of an object. In another embodiment, a global synchronization clock per synchronization node is used. Furthermore, in an embodiment, data integrity is enhanced through the use of snapshots during synchronization processes. In another embodiment, forwarding deletes is used to resolve conflicts in a synchronization process. In another embodiment, update ordering is employed to maintain data integrity when adding or deleting data objects.
摘要翻译：提供了通过减少或防止悬挂参考来保持跨多个设备的数据完整性的方法和系统。在一个实施例中，所有数据对象都具有参考标识，能够引用对象的现存版本。在另一个实施例中，使用每个同步节点的全局同步时钟。此外，在一个实施例中，通过在同步过程期间使用快照来增强数据完整性。在另一个实施例中，使用转发删除来解决同步过程中的冲突。在另一实施例中，采用更新排序来在添加或删除数据对象时维持数据完整性。

摘要： A first method includes requesting a modification of a data object within the data store using a first application process, establishing a read lock on the data object, initializing an object monitor adapted to detects changes to the data object and releasing the read lock, allowing other concurrent processes to write to the data object, wherein the object monitor detects if any of the concurrent processes overwrite the data object. A second method includes requesting a modification of a data object within the data store using a first application process, establishing a read lock on the data store, initializing a datastore monitor adapted to detect changes to the data store, reading all data objects in the data store and releasing the read lock on the data store, allowing other concurrent processes to write to the data store wherein the datastore monitor detects if any of the concurrent processes overwrite one or more data objects in the data store.
摘要翻译：第一种方法包括使用第一应用程序请求在数据存储器内的数据对象的修改，在数据对象上建立读锁定，初始化适于检测对数据对象的改变并释放读锁定的对象监视器，允许其他并发进程写入数据对象，其中对象监视器检测是否有任何并发进程重写数据对象。第二种方法包括：使用第一应用程序请求对数据存储内的数据对象进行修改;在数据存储器上建立读锁;初始化数据存储监视器，适用于检测对数据存储的更改，读取数据中的所有数据对象存储和释放数据存储上的读取锁定，允许其他并发进程写入数据存储，其中数据存储监视器检测是否有任何并发进程覆盖数据存储中的一个或多个数据对象。

摘要： One embodiment of the invention enables nodes or endpoints that have been involved with synchronization of data items to determine which version of a data item (if any) has priority over another version of that same data item. For example, one embodiment of the invention can include a method that can include the determination as to whether any data items have matching identities and conflicting priorities after the synchronization process. Provided a first and second data items have matching identities and conflicting priorities, a determination is made as to whether an indication had been made that the first data item is desirable over the second data item. Provided the indication had been made that the first data is desirable over the second data item, it is indicated that the first data item has priority over the second data item.
摘要翻译：本发明的一个实施例使得已经涉及数据项的同步的节点或端点确定数据项的哪个版本（如果有的话）优先于相同数据项的另一个版本。例如，本发明的一个实施例可以包括一种方法，其可以包括关于在同步过程之后任何数据项是否具有匹配的身份和冲突的优先级的确定。如果第一和第二数据项具有匹配的身份和冲突的优先级，则确定是否已经做出关于第一数据项是否期望超过第二数据项的指示。如果指示第一数据对于第二数据项是期望的，则指示第一数据项具有优于第二数据项的优先级。
