    • Systems, methods, computer program product embodiments and combinations and sub-combinations thereof for data caching and cache synchronization are described herein. An embodiment includes comparing data in a cache with data stored at a data source and determining database operations needed to synchronize one or more partitions of the cache with the data source. Each cache partition is associated with mobile business object (MBO) metadata of a distinct mobile device and the determined database operations are executed to synchronize the partitions with the data source. By refreshing only those partitions which are pertinent to a given device, embodiments of the invention may increase parallelism by allowing multiple partitions to refresh concurrently. The embodiment further comprises reviewing a caching policy associated with the cache. The caching policy may be selected in a manner that reduces data traffic and redundant requests on the data source.
    • 本文描述了用于数据高速缓存和高速缓存同步的系统,方法,计算机程序产品实施例及其组合和子组合。 一个实施例包括将高速缓存中的数据与存储在数据源中的数据进行比较,并确定将高速缓存的一个或多个分区与数据源同步所需的数据库操作。 每个缓存分区与不同移动设备的移动业务对象(MBO)元数据相关联,并且执行确定的数据库操作以使分区与数据源同步。 通过仅刷新与给定设备相关的那些分区,本发明的实施例可以通过允许多个分区同时刷新来增加并行性。 该实施例还包括查看与高速缓存相关联的高速缓存策略。 可以以减少数据流的数据流量和冗余请求的方式来选择缓存策略。
