摘要： A single ended synchronization agent which communicates with a single endpoint. Responsive to instructions from a synchronization manager, a single ended synchronization agent transfers information between its endpoint and a common synchronization engine. Endpoints may include databases, hand held computers, communication links and the like. These novel single ended agent programs in cooperation with a common synchronization engine are able to synchronize databases. The agent programs need not implement synchronization logic and agent programs are required to understand only a single database. These aspects of the single ended agent programs greatly simplify the design, construction and maintenance of this software when compared with the prior art.

摘要： A method and system for synchronization of computer databases using caching agents. In one embodiment, information is accessed from a first database. The information is stored into a persistent store, which may be a permanent media, such as a magnetic disk. The information is retrieved from the persistent store. Such retrieval may be in close time proximity to the storing, or the retrieval may be at a substantially different time from the storing. The synchronization is completed by updating a second database with the information retrieved by the caching agent from the persistent store. As an advantageous result, synchronization of computer databases is more efficient due to an optimized storage format for the information as well as maximum bandwidth access. As a further beneficial result, if a database is not present at the time of synchronization, embodiments of the present invention may enable synchronization capabilities unavailable under the prior art.
摘要翻译： 一种使用缓存代理同步计算机数据库的方法和系统。 在一个实施例中，从第一数据库访问信息。 该信息被存储到永久存储器中，该存储器可以是诸如磁盘的永久介质。 从永久存储中检索信息。 这种检索可能在接近存储的近似时间内，或者检索可能在与存储相当的不同时间。 通过使用缓存代理从永久存储器检索的信息更新第二数据库来完成同步。 作为有利的结果，由于针对信息的优化存储格式以及最大带宽访问，计算机数据库的同步更有效。 作为另一个有益的结果，如果数据库在同步时不存在，则本发明的实施例可以实现现有技术中不可用的同步能力。

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： A method and system for N-way synchronization of computer databases. Synchronization of computer databases is structured into three rounds, namely an agenda round, a query round and a report round. In the agenda round, a synchronization agent software module inquires of a common synchronization engine for updates to the agent's database and provides information as to the level of information in the agent's database. During a query round, a common synchronization engine may request information from databases with new information and distribute that database information to databases needing the new information during a report round. Multiple agents, each representing an associated database may participate a synchronization. In addition, various special purpose agents may also receive, provide and otherwise operate on synchronization information.

摘要： One embodiment of the present invention enables nodes or endpoints 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. Within the present embodiment, when a data item is modified by a node, it is presumed that the modified data item takes priority over the previous version of that data item. Therefore, the “descendant” data item (modified) takes precedence over its “ancestor” data item (previous version). By including this type of “pedigree” information with data items involved with synchronization between different nodes or endpoints, the present embodiment enables the endpoints to determine which version of a data item (if any) has priority over another version of that same data item.
